Washed China Clay Powder

Product Description

Washed China Clay Powder is reckoned for its high density level, stable chemical properties and low porosity level. This soft powder contains hexagonal shaped particles (can be viewed by electron microscope) of kaolinite mineral. Available in cully calcined form, this clay based product has less impurities and it absorbs minimum amount of water. Its refractoriness is high. Its naturally procured version contains minerals like feldspar, quartz and muscovite. Low thermal expansion co efficiency level and low dust content are its key features.

Production of Product:

It is produced by using black clay that goes through a number of procedures like grading, washing, rinsing and removal of impurities.
