Product Description

 

Product Description

Calcined alumina with ultra low sodium alpha
 

Characteristic--------

• White powder or fine sand
• Crystal structure stability
• Insoluble in water
• Difficult to dissolve in acid and alkali solution
• Good thermal stability
• Easy to grind
• Easy sintering

In 2022, a new low-sodium microcrystal production line (Phase I) will be built with an annual capacity of 50,000 tons. Low sodium calcined alpha alumina has the characteristics of lower impurity content, higher purity, lower burning loss, etc., and has good processing performance, mainly used in special glass substrates, structural ceramics, electronic ceramics, high-end refractory materials, polishing
Abrasive materials, lithium battery diaphragm coating industry.
