Higher purity Silicon Nitride

 




Formula for the silicon nitride Si3N4, is an important structural ceramic material.
It is a super-hard material ,lubricity and anti-abrasive.
In addition to hydrofluoric acid, it does not react with other inorganic acids.
And it also resistant to cold shock, even heated to above 1000 ℃ and cooled rapidly,but it will not shatter.
Coating to protect the quartz crucible at a high temperature for the isolation between.quartz crucible and silicon.Liquid silicon can not be reacted with the quartz to ensure the integrity of silicon ingot.
