High Temperature Alumina Ceramic Plates

Our high temperature alumina ceramic plates are flat special ceramic components developed for high-temperature industrial scenarios. They are made of high-purity alumina sintered at high temperature, combining excellent refractory performance and structural strength, and are mainly used as lining plates, sintering bearing plates and heat treatment tools for high-temperature furnaces. Compared with traditional refractory bricks and silicon carbide plates, high temperature alumina ceramic plates have denser and smoother surfaces, do not slag off and do not pollute workpieces at high temperatures, and have outstanding thermal shock resistance. They can withstand frequent temperature rise and fall shocks without cracking, and can be used stably for a long time under working conditions above 1500℃, effectively extending the service life of high-temperature tools.

Our high temperature alumina ceramic plates are prepared by precision dry pressing molding and pressureless sintering process, with uniform green body density and small deformation after sintering. After double-sided precision grinding, the flatness and parallelism reach high precision, and can be directly used as high-precision bearing substrates. The products support customization of different length and width dimensions, thicknesses and special-shaped structures, and can also process positioning holes, diversion grooves and other features on demand. From raw material selection to finished product inspection, we strictly control each process. Each batch of products undergoes high-temperature performance and dimensional accuracy testing to ensure stable quality. At present, they have been widely used in many industries such as ceramic sintering, electronic packaging and metallurgical heat treatment.

We have established a special high-temperature performance control system for high temperature alumina ceramic plates. Each batch of products is sampled for high-temperature refractory test, thermal shock test and bending strength test to ensure that the high-temperature performance of the products meets the standards. During the production process, the molding pressure and sintering curve are strictly controlled to ensure uniform density, no deformation and no hidden cracks of the plate body. 100% full inspection of appearance and dimensions is carried out before packaging to eliminate defects such as chipping and cracking. We support inspection by third-party professional institutions, and the products come with a one-year warranty. Non-artificial quality problems can be returned or replaced.

We support full-process customization services, and can customize high temperature alumina ceramic plates of different specifications and different material formulations according to customers' furnace cavity sizes, bearing requirements and working temperature, and support processing of special-shaped structures such as holes, slots and steps. Our technical team will evaluate the process feasibility in advance and give reasonable structural optimization suggestions. The sample development cycle is 20-30 days, and small-batch trial production is supported. The products support mixed batch customization of different specifications and different thicknesses to meet customers' multi-scenario high-temperature tool needs.

We are an original factory with over ten years of production experience in high-temperature industrial ceramics, with a 3,000㎡ standardized production workshop, equipped with large automatic brick presses, multiple high-temperature tunnel kilns and plane grinding equipment, with a monthly production capacity of up to 5 million ceramic components. The factory has a professional production and technical team of 30 people, which independently completes the whole process from raw material formulation, molding and sintering to finished product processing. It can stably undertake various large-size and large-batch orders for high temperature alumina ceramic plates. The products are exported to many countries and regions such as Europe, the Middle East and the United States.
