Calcium metasilicate Specification

The Wollastonite (Ca(SiO3)), with the CAS registry number 13983-17-0 and EINECS registry number 237-772-5, has the systematic name of calcium oxosilanediolate. It is a kind of white or cream powder, and insoluble in water. And the molecular formula of this chemical is CaH2O3Si.

The physical properties of Wollastonite (Ca(SiO3)) are as followings: (1)#H bond acceptors: 3; (2)#H bond donors: 2; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 57.53 Å2.

Preparation and applications of Wollastonite (Ca(SiO3)): China was the top producer of wollastonite, and it can be obtained by simple screening, but it may contain small amounts of iron, magnesium, and manganese substituting for calcium. Because of its high brightness and whiteness, low moisture and oil absorption, and low volatile content, Wollastonite is very useful. It is usually used in ceramics, friction products (brakes and clutches), metalmaking, paint filler, plastics and so on.

You should be cautious while dealing with this chemical. It irritates to eyes and respiratory system. Therefore, you had better take the following instructions: Do not breathe dust; Wear suitable gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice.

You can still convert the following datas into molecular structure:
(1)SMILES: [Ca+2].[O-][Si]([O-])=O
(2)InChI: InChI=1/Ca.O3Si/c;1-4(2)3/q+2;-2
