Product Description

 

Product Description

Calcined alpha alumina with ultra-low sodium

Primary Uses:

.Semiconductor Manufacturing: Ultra-low sodium calcined alpha alumina is commonly employed in the semiconductor industry, particularly in the production of high-purity silicon wafers. Its low sodium content helps reduce the impact of impurities on semiconductor material performance, ensuring the production of high-quality semiconductor devices.
Ceramic Materials: This type of alumina is also used in the preparation of ceramic materials, such as electronic components for high-temperature environments, ceramic insulators, and ceramic cutting tools. The low sodium content contributes to improved chemical stability and mechanical properties of ceramic materials.
Ultra-High-Temperature Materials: The high melting point and chemical stability of ultra-low sodium calcined alpha alumina make it a crucial raw material for manufacturing ultra-high-temperature materials, such as high-temperature ceramics, refractory materials, and composite materials.
