What is Industrial Ceramic Tray?
Industrial ceramic trays are high-temperature carrier components made from advanced ceramics such as alumina, zirconia and silicon carbide, used to hold parts, powders or fixtures inside furnaces and kilns during sintering, firing, calcining and other heat treatment processes.
Industrial Ceramic Trays vs. Metal and Basic Refractory Carriers
Industrial ceramic trays offer higher high-temperature stability, cleaner contact surfaces, and tighter geometry control than metal or basic refractory carriers, cutting deformation, cracking and contamination in demanding furnace processes and lowering overall cost per furnace cycle.
Industrial Ceramic Trays Properties
Industrial ceramic trays made primarily from advanced ceramics such as alumina, zirconia and silicon carbide, deliver high mechanical strength, reliable thermal stability and good chemical resistance to support demanding high-temperature furnace processes.
Alumina Ceramic Tray
Alumina ceramic tray offers versatile high-temperature performance with good mechanical strength, dielectric insulation and corrosion resistance for general furnace processes.

Industrial Ceramic Tray Applications
Industrial ceramic trays are used as high-temperature carriers for parts, powders and fixtures in furnaces and kilns across powder metallurgy, technical ceramics manufacturing, industrial heat treatment and R&D lines, helping stabilise loading, support repeatable cycles and reduce deformation and contamination of the products being processed.
Powder Metallurgy/ MIM Sintering
🧩Where industrial ceramic trays are used:
Industrial ceramic trays sit on the furnace hearth, kiln car, pusher plate or belt as carriers for pressed compacts and MIM green parts through debinding and sintering. Parts are loaded directly on the tray or on setters placed on the tray.
🧩What ADCERAX trays help solve:
ADCERAX industrial ceramic trays provide flat, reinforced support that reduces distortion and warpage under load. Clean contact surfaces and repeatable tray geometry help cut contamination, scrap and rework.
Technical Ceramics Firing
🧩Where industrial ceramic trays are used:
Trays and setter plates are positioned on kiln shelves or cars to carry substrates, rings and structural ceramics during firing and cooling. They form the interface between the parts and the furnace support system.
🧩What ADCERAX trays help solve:
ADCERAX firing trays and setters help control flatness and edge quality with smooth, engineered support surfaces. Consistent dimensions and stacking logic stabilise loads and improve firing uniformity.
Industrial Heat Treatment / Calcining
🧩Where industrial ceramic trays are used Industrial ceramic trays serve as rugged carriers for bulk parts, fixtures or powders in box furnaces and kilns that run repeated thermal cycles. They are moved in and out as reusable loading units.
🧩What ADCERAX trays help solve
ADCERAX trays are designed to handle heavy loads and frequent cycling with reduced warpage and cracking. This improves furnace uptime, makes loading more predictable and lowers cost per cycle.
R&D and Pilot Thermal Processing
🧩Where industrial ceramic trays are used:
In lab and pilot furnaces, industrial ceramic trays hold varied samples and small batches on shelves or small kiln cars, often with changing layouts as tests evolve.
🧩What ADCERAX trays help solve
ADCERAX trays give R&D teams stable, reusable platforms that are easy to adapt with different shapes or grooves. This reduces improvised supports, lowers sample damage risk and simplifies later scale-up to repeatable production trays.

Holding ceramic tray wall variation within narrow bands for stable heating and cooling behaviour.
Controlling side-wall straightness and base flatness to ensure smooth stacking and good contact with shelves or supports.
Machining rims and ends so ceramic trays fit fixtures and carriers correctly, improving handling strength and alignment.
Clean, Low-Contamination Surface Finishing
Internal and external industrial ceramic tray surfaces are finished to reduce residue build-up, minimise contamination and limit micro-cracks, helping each firing cycle stay clean and easy to maintain.
Smoother inner surfaces reduce powder adhesion and make cleaning easier between runs.
Removing sharp rims and micro-chips to lower chipping risk during loading, unloading and tong handling.
Selected surface treatments further lower porosity, supporting cleaner operation where reduced contamination is required.
High-Temp Sintering for Service Life & Thermal Shock Resistance
Microstructure density and strength in industrial ceramic trays are developed through controlled firing cycles, tuned to each material system for long life under heating and cooling.
Managing ramp and cool-down rates to balance strength, density and resistance to cracking.
Matching soak times and peak temperatures to the chosen tray material to build reliable service life over many cycles.
Low open porosity improves mechanical stability and cuts powder contamination over many cycles, helping trays deliver long-term value.
FAQs About Industrial Ceramic Tray
Industrial ceramic trays can be produced in different advanced ceramics such as alumina-based, zirconia-based or silicon-carbide-based bodies; ADCERAX recommends a material after reviewing your temperature, atmosphere and loading conditions.
The safe range depends on the ceramic material and atmosphere, but typical working temperatures for industrial ceramic trays are:
Alumina ceramic tray – commonly used around 1,400–1,650 °C in air, depending on grade and load.
Zirconia ceramic tray – typically used around 1,200–1,400 °C in air where high strength and toughness are needed.
Boron nitride ceramic tray – usually used up to about 900–1,000 °C in air, and higher (up to around 1,800–2,000 °C) in inert or vacuum atmospheres.
Silicon carbide ceramic tray – often used around 1,400–1,600 °C in air, with higher limits in controlled or inert atmospheres.
Final allowable temperatures should always be confirmed against your specific furnace atmosphere, cycle profile, tray design and safety margin.
Thicker, rib-reinforced trays are used for wide spans and heavy loads, while thinner or lighter trays are used when weight and heating speed are more important; sharing your furnace dimensions and load map allows an optimised recommendation.
Geometry
A ceramic tray is usually a low, open, flat carrier; a ceramic sagger has side walls and sometimes a lid or cover.Function
Ceramic trays focus on supporting and positioning parts on shelves or kiln cars, while saggers focus on protecting and containing the load.Process control
Saggers help control contamination, gas flow and powder movement, especially for sensitive powders or reactive parts; open trays allow more direct atmosphere contact and easier loading/unloading.Typical use
Trays are chosen for general sintering or heat treatment where open support is enough; saggers are used when the product needs shielding, separation or a controlled micro-environment during firing.
By keeping parts supported on flat, stable surfaces and resisting warpage, ceramic trays lower deformation, cracking and contact marks, which reduces rework and scrap in repeated furnace runs.
Yes. You can send 2D/3D drawings or samples, and ADCERAX engineers will review dimensions, tolerances and process data, then provide a manufacturable tray design and quotation.
Key data include tray dimensions, structure (grooves, ribs, holes, walls), temperature profile, atmosphere, load weight per tray, expected cycles and target quantity for samples and production.
Typical industrial tolerances are in the ±0.1–0.3 mm range on critical dimensions, depending on size and geometry; ADCERAX confirms achievable tolerances after evaluating each design.
Service life depends on temperature, loading, handling and atmosphere; with appropriate design and operation, trays can run many cycles before replacement, and ADCERAX can help estimate life based on your current experience.
In many cases yes, but it is often better to review and adjust tray thickness, reinforcement and support points to fully benefit from ceramic performance and avoid unexpected stress points.
ADCERAX supplies round trays, rectangular trays, round saggers, square saggers and special geometries with grooves, partitions or stepped surfaces to match specific loading patterns.
