1. High Temperature Resistance: Alumina trays are capable of withstanding extreme temperatures, often exceeding 1700°C. This makes them ideal for use in high-temperature environments such as furnaces and kilns. 2. Chemical Stability: Alumina trays is highly resistant to chemical corrosion and does not react with most acids, alkalis, or molten metals. This ensures that the trays maintain their integrity in harsh chemical environments. 3. Mechanical Strength: With excellent mechanical properties, including high hardness and wear resistance, alumina trays are durable and can withstand heavy loads without deforming. 4. Electrical Insulation: Alumina trays is an excellent electrical insulator, which makes these trays suitable for applications where electrical conductivity must be minimized. 5. Thermal Shock Resistance: Alumina trays can endure rapid temperature changes without cracking or breaking, which is crucial in processes involving quick heating and cooling cycles.

Applications of Alumina Trays

1. Laboratory Equipment: Due to their chemical inertness and thermal stability, alumina trays are commonly used in laboratories for high-temperature experiments, chemical reactions, and material testing.

2. Industrial Furnaces and Kilns: Alumina trays are often used as components in industrial furnaces and kilns, where they support materials during heat treatment processes such as sintering, calcination, and annealing.

3. Ceramic Manufacturing: In the production of other ceramic components, alumina trays serve as platforms for firing and sintering, ensuring consistent quality and preventing contamination.

4. Metalworking and Metallurgy: Alumina trays are employed in metallurgical processes for handling and treating molten metals, especially in environments where high temperatures and corrosive conditions are prevalent.

We only make high purity alumina ceramics

1. High-purity alumina content 99.3% -99.5%, other alumina ceramics 92% -99%.

2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color.

3. Alumina is a refractory material, the higher the purity, the better the refractory effect.

4. After high-purity alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ℃ ~ 1800 ℃.

5. The volume density of high-purity alumina> 3.92 g / cm3 has a smooth surface and is not easily corroded by chemicals. The bulk density of other ceramics is> 3.70 g / cm3 ~> 3.85 g / cm3.

6. High purity alumina has good hardness and good wear resistance.

7. High purity alumina products have a longer service life.
