99.9% High Purity Alumina Ultrafine Powder BET 10-20

Due to the high chemical purity, small grain size, large specific surface area, and good sintering performance of alumina, high-quality ceramic materials, electronic devices, and optoelectronic devices can be prepared. It can also be used to prepare high-performance materials such as high-temperature ceramics, electronic ceramics, and high-temperature thermal barrier coatings.

【Application】

It is mainly used for the ceramics/battery coating.

【Specification】

1. Chemical properties: Al₂O₃>99%

2. Color:white

3.PSD: D50=0.8-1.2um,D99<6um

【Product features】

Lithium ion batteries with alumina separator is fabricated for safety improvement. Alumina separator is coated on electrode by a scalable and cost-effective method.Lithium ion batteries with alumina separator perform better than conventional cells.

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.
