Yongzhou Mingrui Ceramic Technology Co., Ltd produces custom alumina ceramic plates with alumina purity ranging from 95% to 99.99% Al2O3, tailored to dimensional specifications provided by buyers. The plates are manufactured as panels, discs, or boards using isostatic pressing and high-temperature sintering, achieving tight tolerances suitable for precision applications. Surface finish and thickness vary per order, with common thicknesses between 0.5mm and 20mm, and flatness typically held within ±0.05mm for high-purity grades.
The material composition is based on sintered alumina, with higher purity grades offering improved electrical insulation, thermal shock resistance, and wear performance. Grades above 99% Al2O3 are typical in semiconductor and high-vacuum environments, while 95% to 97% grades are standard in industrial wear components and insulating substrates. The material exhibits low thermal expansion and maintains structural integrity up to 1700°C in inert atmospheres. No organic binders or additives are used in the base formulation.
These plates are sourced by manufacturers in electronics, aerospace, and chemical processing for use as substrates, insulators, wear pads, and furnace linings. Buyers typically require custom dimensions, hole patterns, or surface treatments such as metallization or grinding. Trade terms are negotiated per order; standard packaging includes foam-lined cardboard boxes with desiccant, and lead times range from 15 to 30 days depending on complexity. MOQ is not listed and must be confirmed directly with the supplier.

Before placing an order, verify the exact alumina purity grade required for your application, as performance varies significantly between 95% and 99.99%. Confirm that the supplier can meet your dimensional tolerances, surface finish, and edge treatment needs. Request a sample for mechanical and electrical testing, especially if the plates will be used in high-reliability environments like aerospace or semiconductor manufacturing. Do not assume standard specs apply without written confirmation.
Lead time typically ranges from 15 to 30 days, depending on customization complexity and batch size. Incoterms are not listed; confirm whether FOB Ningbo, CIF, or EXW applies. Payment terms are likely T/T in advance or LC, but must be negotiated directly. Packaging must include moisture control and individual plate separation to prevent chipping during transit. Always request a packing list and material traceability code per batch.
Quality verification should include a certificate of analysis for alumina content, density, and flexural strength. Inspect samples for surface defects, microcracks, and dimensional accuracy using calibrated tools. Request test reports for thermal shock resistance if used in cycling environments. Ensure documentation includes batch numbers for traceability. If used in regulated industries, confirm whether material certifications can be provided under your quality system requirements.
