Alumina Tray Description

In the realm of laboratory and industrial applications, high-purity alumina products stand as indispensable tools, renowned for their exceptional properties and wide-ranging versatility. These products, encompassing alumina trays, plates, dishes, boat crucibles, combustion boats, and ceramic crucibles, offer a unique blend of durability, thermal stability, and chemical resistance, making them ideal for a diverse spectrum of tasks.

Precision-square alumina tray with 90° ±0.2° angles, designed for automated wafer handling systems, compatible with SMIF pods

Alumina tray crafted from high-purity alumina, provide a versatile platform for laboratory and industrial applications. Their exceptional thermal conductivity facilitates efficient heat transfer, while their resistance to chemical attack safeguards the integrity of experiments and production processes. Whether used for chemical calcination, metal casting, or ceramic sample preparation, alumina trays seamlessly adapt to diverse needs.

Alumina trays have excellent thermal conductivity, which helps to transfer heat efficiently. In addition, they can withstand temperatures up to 1600°C, and their strong chemical resistance helps to protect the integrity of experimental and production processes.

Detailed application introduction

High temperature furnace application: Alumina trays can withstand extremely high temperatures and are essential components in high temperature sintering furnaces, heat treatment furnaces and experimental furnaces. These trays can provide strong and durable support capabilities and can maintain their shape at high temperatures without deformation.

Electronic component manufacturing applications:During the manufacturing process of electronic components, alumina trays carry semiconductor chips, capacitors, resistors, and other parts. They ensure stable support and excellent insulation even 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.
