Product Introduction:

4N HPA (High Purity Alumina) is a white powder with uniform particle size, easy dispersion, stable chemical properties, moderate high temperature shrinkage, good sintering performance, high conversion rate and low sodium content. High purity alumina is the basic raw material for various high-end products, such as sapphire crystal, advanced ceramics, polishing slurry, lithium battery separator and other products. 

The products are of reliable quality, with high melting point, good thermal stability, high hardness, good wear resistance, high mechanical strength, good electrical insulation, corrosion resistance, etc. We can provide 4N HPA with different particle size and crystalline structure by controlling the production process according to different applications and requirements.

Characteristic of 4N HPA:

1) High purity and low chemical composition.

2) High dispersion.

3) Controllable particle size and crystal form.

4) Chemical Resistance.

Application:

High purity alumina has a melting point of 2050℃ and is mainly used for LED artificial sapphire crystals, advanced ceramics, phosphors, polishing slurry and some high performance materials. As raw materials for sapphire crystals, we can provide powder, granule, block or column according to different requirements.

 

Production Process:

4N HPA is produced by the Bayer process. The Bayer process is mainly divided into three stages: dissolution, decomposition and calcination. It is mainly composed of crushing and wet grinding, bauxite dissolution, red mud separation and washing, sodium aluminate solution plus seed decomposition, and aluminum decomposition mother liquor. Evaporation, sodium carbonate caustic recovery in alumina production, aluminum hydroxide calcination and other processes.

 

Packing&Storage:

We usually use 25kg kraft bags packed and 40 bags packed on a 1.1m*1.1m pallets and with wrapping film. We also can pack the goods according to customers requirements, including the materials and size of bags and pallets. 

With the aim of pursuing zero-defect quality, we strive to provide customers with cost-effective and high grade Good Electrical Insulation High Pure Alumina Fluorescent Tube Powder Hpa High Purity Alumina. In order to remain invincible in the fierce market competition, we always adhere to the service concept of high quality and fast delivery. We look forward to more and more new partners to do business with us and benefit from each other. Our company's advantageous geographical location and convenient transportation are conducive to the efficient allocation of logistics.
