*The table above shows typical properties for common alumina tray materials only. The properties of custom ceramic trays will vary depending on the purity and process selected.
Wide range of applications
High temperature furnaces: Alumina trays can withstand extreme high temperatures and are used in high temperature sintering furnaces, heat treatment furnaces and experimental furnaces. As trays for carrying and supporting materials, they are durable and not easy to deform.
Electronic component manufacturing: In the process of electronic component manufacturing, alumina trays can be used to carry electronic components such as semiconductor chips, capacitors and resistors to ensure stability and insulation at high temperatures.
Metal and ceramic powder sintering: The thermal conductivity of alumina trays is about 25-30 W/m·K (at room temperature). It can be used for the sintering process of metal powders and ceramic powders. The shape and superior performance of the tray can ensure that the materials can be evenly heated and treated at high temperatures.
Chemical experiments and production: In chemical experiments and production, good corrosion resistance allows ceramic trays to be used to carry chemical reaction materials and samples.
powerful
We have a professional advanced ceramic production plant with 15 years of professional experience and many technical research results in the production of advanced ceramics. We have a variety of advanced ceramic products with crucibles for you to choose from, such as alumina boats, alumina crucibles, alumina trays, etc.
We only produce high-quality advanced ceramic products, using the best raw materials and equipment. In the preparation of raw materials, we use alumina to grind to submicron particles.
In the molding process, we use a variety of advanced equipment, such as injection molding machines, isostatic pressing machines (CIP), hot pressing machines, etc. These equipment and the operation of our professionals ensure the quality of alumina ceramic products.
Sintering is a very critical step in the ceramic manufacturing process. We use a rapid sintering furnace (RAPID) to ensure quality while greatly shortening the ceramic sintering cycle. We also have microwave sintering furnaces, hot isostatic pressing furnaces (HIP) and other equipment for the sintering of different alumina ceramics. Our professionals strictly and accurately control the ceramic sintering time and temperature to further improve the performance of alumina ceramics.
