Substrate/substrate material: alumina, sapphire

 Sapphire will be used as the substrate/substrate in many material production, including semiconductor. The main raw material consumed in the production of sapphire crystal is high-purity aluminum oxide. high-purity aluminum oxide powder can improve the purity and transparency of sapphire crystal, thereby improving the performance of sapphire materials.
 
【Application】
 
The substrate itself may have some special functions and uses, or it may only be used as a substrate for new materials, and it has no other special uses. In the past, the materials used as film substrates were glass, ceramics and metal plates, but now the mainstream are sapphire, Si and SiC
 

【Specification】

1. Chemical properties: Al₂O₃>99.9%
2. Color:white
3.PSD: D50=0.5-0.8um,D99<4um

【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

The alumina ceramic coating provides a skeleton for the flexible seperator, improves the wear resistance of the seperator, prevents lithium dendrite from piercing, reduces heat shrinkage, improves temperature resistance, and the pores are stable with temperature, which can effectively improve the safety performance of the 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.

1 Q: How about the packing?
