*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.
