Sibelco - Wollastonite | Products

Wollastonite is a calcium inosilicate mineral (CaSiO3) that may contain small amounts of iron, magnesium and manganese substituting for calcium. Some of the properties that make wollastonite so useful are its high brightness and whiteness, low moisture and oil absorption, and low volatile content.

Silica

Apparently very fine grades of silica aid in cristobalite formation in stoneware bodies (cristobalite is a form of silica that goes through it's inversion at about 200C). When limestone and silica are available in a body they can react to form wollastonite. This adds mechanical strength and is exploited in tile bodies.

Low temperature production of wollastonite from limestone ...

The α-wollastonite phase was fully obtained at a limestone/silica sand molar ratio of 1:1, sintered at 1450 °C for 4 h, with a dense microstructure and olivine as a minor phase. Purity of the raw materials, molar ratio of limestone/silica sand and firing temperature all had an influence on the final product of calcium silicate materials.

Mohs' Hardness (Typical) of Abrasives

Abrasive Definitions: Steel shot and steel grit are considered hard abrasives. Steel abrasives are measured in Rockwell C hardness. They are produced in hardness ranging from 42 to 65. Steel grit provides an etch on a steel substrate, whereas steel shot provides a peened surface on a steel substrate.
