Calcium silicate board is a kind of light weight building materials made by siliceous (mainly quartz powder and diatomite),calcareous (mainly camenet lime) and rainforcedfiber (include pulp fiber, glass fiber, gypsum, ect), by a serious process such as pulping, molding, steamling, surface and so on.　

It is of every stable performance because of torbay mullite crystal Synthesed by siliceous and calcareous materials under High Temperature and High Pressure　condition．

Calcium silicate board is of good performance such as fire proof, moistureproof, durable, no deforming, heat insulation and so on, especially suitable for building internal wall board and ceiling materials.
