Product Description

 

Product Description

High Purity Calcined Alumina Powder

1. Technics: Calcined temperature beyond 1300C, the alumina powder be calcined without Boron, Ultimate crystal size 3-5um. 

2. Delivery time: Within 2 weeks to ship since the date we receive your deposit or L/C at sight. 

Alumina has high strength, high hardness, high temperature resistance, corrosion resistance and wear resistance, it is used as the ceramic material in production. Calcined Alumina is specially produced for refractory enterprises, with high conversion, high fluidity, good dispersibility, uniform particle size and so on. Application: - Used as the main raw material for the high quality refractory products, as well as fine ceramics and polishing products. - Used in the ceramic industry, it can be easy to sintering, sintered dense, good volume stability and other characteristics. -Calcined Alumina Widely used in high aluminum refractory, high aluminum refractory fireball, corundum brick, grinding and polishing, refractory brick, alumina ceramic, etc.

We are one of the earliest large-scale production of calcined alpha alumina enterprises in China. The domestic market share ranks first and the global market share ranks third. The product consists of medium and low sodium large primary crystal and low sodium microcrystal calcined α alumina
And activated alumina, easy grinding calcined alumina, etc., to meet the different application needs of ceramic and refractory industry.
