Product Description

Industrial Grade Sapphire Substrate Small Granularity Alumina Powder

 

 

  Sapphire is composed of aluminum oxide (Al2O3), which is formed by covalent bonding of three oxygen atoms and two aluminum atoms. Its crystal structure is a hexagonal lattice structure. It is commonly used in A-Plane, C-Plane, and R-Plane. Due to its wide optical transmission band, sapphire has good transparency from near-ultraviolet (190nm) to mid infrared light. Therefore, it is widely used in optical components, infrared devices, high-strength laser lens materials, and mask materials. It has the characteristics of high sound speed, high temperature resistance, corrosion resistance, high hardness, high transparency, and high melting point (2045 ℃). 

 

Application

 

Excellent light transmission, so it is widely used in optical elements, infrared devices, high-strength laser lens materials and light cover materials.

  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.
