Alumina Powder for improving the compactness of ceramics

 
  The hardness of corundum powder is high. It can be used as abrasive, polishing powder and high-temperature sintered alumina. It is called artificial corundum or artificial gem. It can be used to make diamond in mechanical bearing or watch. Alumina is also used as high-temperature refractory material to make firebrick, crucible, porcelain, artificial gem, etc
 
【Application】
It is mainly used for the coating material of positive and negative pole diaphragm of lithium battery, which is beneficial to the stability of the battery.
It is suitable for Lithium ion battery separator,and the battery can be used for electronic car, electronic intelligent products and energy storage products.

【Specification】
 
1. Chemical properties: Al₂O₃>99%
2. Color:white
3. PSD: D50=0.8-1.2um,D99<6um

 

 
【Product features】
 
  The presence of the alumina can significantly improve the physical and chemical properties of battery separators. The alumina coating layer may reduce or prevent dendrite puncture, lithium plating and separator shrinkage during over-heating, hence significantly increasing safety performance for a lithium ion battery.

1. Less magnetic foreign matters, stable electrical performance, low content of harmful ions;
2. High heat resistance, stable at high temperature;
3. The particle size distribution is very narrow, which can be coated with a very thin thermal insulation coating, with low thermal resistance; no small particles blocking Li + ion channel, no coarse particles scratching the film.
 

 
【Packing】 25kgs/poly-drum ,500kgs/pallet.
