Zirconia Ceramic Crucible | YSZ & MSZ Crucibles for Melting, Calcination & Lab Use
ADCERAX specializes in zirconia ceramic crucibles engineered for extreme thermal conditions — the high-temperature, low-contamination route when quartz softens, graphite burns off or porcelain contaminates the sample. Our crucibles serve metal melting, powder calcination and laboratory furnace work in vacuum, inert and oxidizing atmospheres.
From yttria-stabilized (YSZ) to magnesia-stabilized (MSZ) routes, we supply standard and drawing-based custom crucibles with engineering review before quotation: send your dimensions or an old-part photo with temperature, atmosphere and the material you load, and we will confirm the right route and typical lead time.

What is a Zirconia Crucible?
A zirconia crucible is a container made from stabilized zirconium oxide (ZrO₂) — yttria-stabilized (YSZ) or magnesia-stabilized (MSZ) — for very high-temperature, chemically aggressive use. Its usable temperature depends on stabilizer route, atmosphere (air, vacuum or inert) and thermal cycling, so we confirm the working range by review rather than quote a single fixed ceiling. It is used to melt precious metals, sinter and calcine ceramic or battery powders, and hold samples in lab furnaces.
Because zirconia is thermal-shock sensitive, we review heating/cooling rate, wall thickness and shape against your furnace cycle before confirming a design.

Custom Zirconia Crucibles, Made to Your Drawing
ADCERAX makes custom zirconia crucibles to your drawing or old-part photo — cylindrical, conical, rectangular, boat, with-lid and non-standard shapes. Send your temperature, atmosphere and loaded material, and our engineers confirm the material route, feasible geometry and a typical lead time.
Customization Options
Cylindrical, conical, rectangular, boat, with-lid or fully custom forms, in the capacity and dimensions your furnace needs.
Capacity, OD, ID, height and wall thickness set together — wall and geometry reviewed for thermal-shock resistance, not guessed.
YSZ (Y-TZP) for the main high-temperature route, or MSZ where thermal cycling is severe. We confirm the route for your load — no default stabilizer assumed.
Lids, pour geometry and a smooth, low-contamination surface — matched to your melt, powder or sample so purity is protected.
Customization Process
Share a drawing, CAD or old-part photo with temperature, atmosphere, load and quantity.
Engineers review manufacturability and thermal-shock risk, then confirm route, shape and lead time.
Prototype first if needed, then batch production with dimensional and density checks on every batch.
Protective packing for fragile ceramics, with worldwide shipping and full documentation.
One-Stop Zirconia Crucible Manufacturing
When a standard size doesn't fit or your supplier discontinued a part, we rebuild it to drawing — custom capacities, shapes, lids and wall designs, including hard-to-source geometries other suppliers turn down.
Reviewed Before You Commit
Send a drawing or old-part photo with your working conditions. We confirm the route, shape and lead time before you order — catching cracking and contamination risks up front.
Prototype to Repeat Supply
Crucibles are consumables — a single-sourced part stalls production. We support trial batches, annual repeat supply and OEM packs, with the same route and inspection every batch.
Direct Factory Communication
You talk directly to the engineers who make the crucible — no trading-company middleman. Questions on route, feasibility or lead time get a straight answer from the people running the build.

Frequently Asked Questions About Zirconia Crucibles
A zirconia crucible maintains structural stability toward ≈2200 °C in vacuum or inert atmospheres (≈1900–2000 °C typical in air), preventing collapse during melting cycles. It also resists wetting by noble metals, reducing material loss. This makes it reliable for platinum, palladium, and high-value alloys.
Zirconia is a strong but thermal-shock-sensitive ceramic: rapid heating or quenching can crack any zirconia crucible if the cycle is too aggressive. That is why we review your heating and cooling rates, wall thickness and crucible shape before confirming a design, and why the magnesia-stabilized (MSZ) route is offered for harsher cycling. Controlled ramp rates — rather than a blanket "crack-proof" promise — are what deliver long service life.
Zirconia crucibles offer good resistance to many acids, alkalis, molten salts and slags, which protects both crucible and sample from contamination. There are exceptions — for example hot concentrated sulfuric environments — so we confirm compatibility against your exact chemistry before quotation.
Arc shaped crucibles are used in reactors and furnaces requiring even heat distribution. They support material sintering where curved surfaces reduce stress concentration. These are common in research-scale and pilot plants.
Rectangular crucibles provide wide, flat surfaces that ensure even powder distribution during sintering. They are favored for consistent results in material science studies. Their geometry improves heating uniformity across small samples.
Yes — zirconia crucibles and sintering trays are used for calcining cathode powders and sintering battery materials, where a low-contamination, corrosion-resistant container matters. Compatibility is confirmed against your specific lithium chemistry, firing temperature and cycle before we recommend a design.
Round zirconia trays are widely used in dental labs for block sintering. Their smooth surfaces prevent micro-cracks in zirconia dental crowns. This ensures high precision in restorative ceramic production.
Service life depends on thermal cycling intensity, heating rates, atmosphere and handling. As a typical reference, well-matched crucibles in moderate cycling can serve through many dozens of firing cycles, while aggressive quenching shortens life sharply. Share your furnace cycle and we will recommend the route (YSZ or MSZ) and wall design that lasts longest in your process.
Yttria-stabilized zirconia (YSZ) is the standard route for most melting, calcination and lab work, offering high strength and density. Magnesia-stabilized zirconia (MSZ) trades some strength for better tolerance of harsh thermal cycling, making it worth reviewing when your process involves faster ramps or repeated quenching. Tell us the temperature profile and loaded material, and we will confirm the right route.
Send us the shape and capacity (or a drawing / old-part photo), working temperature and atmosphere, the material you melt or fire, and quantity. ADCERAX reviews the material route and manufacturability first, then replies with what we can make and the typical lead time — engineering review always comes before quotation.
