| Silicon dioxide optical coating material is made of high purity silicon dioxide powder as raw material and adds appropriate useful elements to effectively control hazardous substances in silicon dioxide. It is melted under a temperature of above 2000 ˇăC and crushed after precise annealing.
The material is high hardness and can be used in surface protection. It is widely used in optical filter lens production due to its small stress and easy filming, beside there is no other material which can replace silicon dioxide coating system and It is applied in ultra large scale integrated circuits in large quantity due to its also good electrical insulation.
