What Is an Ceramic Plate?
Ceramic Plates are engineered from high-purity oxide material , combining excellent hardness, thermal stability, and electrical insulation. Manufactured via advanced pressing and sintering processes, they maintain structural integrity in corrosive and high-temperature environments.
Key Features & Benefits
Ultra-High Purity (≥ 99%) ensures minimal impurity interference in electronic and optical applications.
High-Temperature Resistance up to 1750 °C reduces deformation and thermal shock risk.
Superior Wear & Chemical Resistance extends component lifetime in abrasive or corrosive settings.
Low Thermal Expansion (≈ 7.2 × 10⁻⁶/°C) minimizes stress during rapid heating/cooling cycles.
Excellent Electrical Insulation (dielectric strength ≥ 12 kV/mm) ideal for substrate and insulator roles.

Applications of Ceramic Plate
FAQs About Ceramic Plate
Yes, absolutely. We specialize in providing Custom Ceramic Plates. You can specify dimensions, thickness, purity levels (e.g., 96% Al2O3, 99.5% Al2O3, >99.7% Al2O3), surface finishes, and complex features like holes, slots, or chamfers for your Al2O3 ceramic plate.
We offer Ceramic Plates in various purity levels to suit different application needs and budgets. Common purities include 96% alumina, 99% alumina, 99.5% alumina, and high-purity alumina plates at 99.7% or even 99.9%. Higher purity generally enhances properties like chemical resistance and electrical insulation.
The thickness for an Alumina Ceramic Base Plate can vary significantly based on the application, from very thin (e.g., 0.25mm for substrates) to quite thick (e.g., 50mm or more for structural components). We can manufacture your alumina plate to precise thickness specifications.
To order a High Purity Alumina Plate or a custom-designed technical ceramic plate, you can contact us directly through our website's RFQ form, email, or phone. Please provide your specifications, including dimensions, purity, quantity, and any drawings for custom parts. Our team will then assist you with a quote and lead time.
While Alumina Oxide Ceramic Plates are extremely hard, they can be precision machined after sintering using diamond grinding and lapping techniques. This allows us to produce precision alumina substrates and plates with very tight dimensional tolerances, complex features, and specific surface finishes (e.g., polished, lapped) to meet demanding application requirements.
