High Purity Sub-micron Silicon Nitride Powder Used in The Thin Film Solar Cells

The performance of the silicon nitride powder:

1. High temperature stability,

2. Thermal shock resistance

3. Chemical stability

4. Good electrical insulation

The application for silicon nitride powder:

1. Silicon nitride powder as an engineering ceramic material, which is widely used in industry. Mainly used for ultra-high-temperature gas turbines, aircraft engines, turbine blades, heat exchangers, furnaces, etc. Heat-resistant coating can also be used for rockets and nuclear reactors.

2. For insulation materials, machinery wear-resistant materials, heat engine materials, cutting tools, advanced refractories and anti-corrosion, abrasion sealing components. Silicon nitride ceramic gas turbine combustor do, mechanical seal rings, transmission of electromagnetic pump liquid aluminum pipes and valves, permanent mold, steel separation ring.

3. Use of silicon nitride ceramics good electrical insulation and resistance to thermal shock resistance can be used to make glow plugs, ignition can use it for car engine starting time is shortened, and can quickly start the car in cold weather. There are good through the silicon nitride ceramic microwave properties, dielectric properties and high-temperature strength, as missiles and aircraft radomes.

4. Used for fine ceramics sintered materials, corrosion, abrasion, abrasive materials.

5. Can be applied to the silicon nitride thin film solar cells. After plating by PECVDsilicon nitride film as an antireflection film is not only possible to reduce reflection of incident light, and, during the deposition of the silicon nitride film, the reaction product into a hydrogen atom and a silicon nitride film, played a role in the passivation of defects.
