High Temperature Resistance Nano Grade Alumina Polishing Powder High Purity

In the field of advanced composite materials, the application of nano alumina additives is becoming increasingly common. For example, in the aerospace field, the addition of nano alumina additives to high-performance polymers with extremely strict performance requirements can ensure that materials maintain reliable performance and excellent mechanical strength in extreme high temperature cosmic environments, ensuring the safe operation of spacecraft and the smooth completion of various tasks.

【Application】

It suit for High Temperature Resistance

【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.
