Higher purity quotient nano grade Alumina polishing powder

In addition to many excellent characteristics such as high hardness, high strength, corrosion resistance, wear resistance, high temperature resistance, high insulation, and high oxidation resistance, alumina has more excellent physical and chemical properties than ordinary alumina due to its strong volume effect, quantum size effect, surface effect, and macroscopic quantum tunneling effect.

【Application】

It suit for Electronic Optics and Laser Crystals.

【Specification】

1. Chemical properties: Al₂O₃>99.9%
2. Color:white
3.PSD: D50=50-100nm

【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.
