The Basis for Solar Energy Industry - Crystalline Silicon
At the moment, crystalline silicon (polycrystalline silicon and monocrystalline silicon) is the main material for solar energy industry. The market share is more than 90% and it will keep the important status for a relatively long time. The application of crystalline silicon is almost for semiconductor and solar cell. According to the purity, they can be devided into electronic grade and solar energy grade. With the high-speed development of solar energy, the demand of crystalline silicon for solar cell is more than for semiconductor.
Boron Nitride Ceramic in Crystalline Silicon Production
Boron Nitride Ceramic is one kind of advanced ceramics which is suitable for vacuum or innert gas condition. It has excellent thermal properties like high temperature resistance, high thermal conductivity, low coefficient of thermal expansion (high thermal shock resistance) and good electrical property, it is the best ceramic material using for high temperature insulation. The character of machinability enable it to be made into high precision parts. Therefore, boron nitride is usually used for rapid heating equipments, as insulating parts for polycrystalline silicon ingot furnace. The heating elements will be protected by boron nitride parts in high temperature furnace.
Properties for Boron Nitride:
*Excellent thermal shock resistance
*High electrical resistivity
*Low density
*High thermal conductivity
*Isotropic (thermal conductance is different in different planes)
*Corrosion resistant
*Good chemical inertness
*High temperature material
*Excellent lubricating properties
*Low coefficient of friction
*Non-wetting (without oxidization)
*High dielectric breakdown strength
*Excellent Machinability
