Silicon carbide boat holder
Main features
Silicon carbide boat holder has a stable structure, good material thermal stability performance, no deformation during high-temperature use, and an ultra long service life, effectively solving the problem of bearing component loss under high load capacity of photovoltaic cells.
Application industry
Quartz boat holders and boats commonly used in the photovoltaic industry have a service life of 3-6 months due to their production process and quartz material characteristics. Silicon carbide boat holders and boats, replacing quartz, can have a service life of more than 5 years, significantly reducing usage costs and production capacity losses caused by maintenance and repair downtime.
Application scope
Silicon carbide boat holder and boats is a key load-bearing component suitable for photovoltaic grade cell diffusion process equipment.

Black silicon carbidedescription Black silicon carbide is produced at high temperature in an electric resistancetype furnace with quarts and petroleum as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive. Company introduction Our company was established in 1976, is a famous manufacturer of abrasive powder in china.

The advantages of silicon carbide refractory castable lie in its high heat conduction, low thermal expansion, and no reaction with slag. It has been used as slag reaction and high temperature peeling kiln site for a long time. The disadvantage of silicon carbide refractory is that the chemical properties are very unstable under certain atmosphere.In oxidation gases such as oxygen, water vapor, carbon monoxide, carbon dioxide) easy to corrode, iron oxide, etc, are easy to be in the hot metal and vacuum oxidation decomposition, the downside is that the refractory castable with carborundum dissolved water, in water system such as castable monolithic refractories, sometimes illiquid caused the density of silicon carbide refractory castable is bad, the third weakness is lack of sintering, hard to get high strength, but sometimes it is difficult to produce sintering and contraction, in monolithic refractories is a virtue.
