Our annual output is more than 200,000tons. We have built our own laboratory to control the quality during all the processing procedures from sorting and grinding to package.Inston’s mission is to provide customers with wollastonite of stable quality, abundant and in time delivery. The aim of Inston is to provide wollastonite solution to the worldwide customer.
Product 1: Wollastonite
Wollastonite is a kind of calcium silicate mineral (CaSiO3), It is usually white. Some of the properties that make wollastonite so useful are its acicular structure, high brightness and whiteness, low moisture and oil absorption, nontoxic, no pollution and chemical stability.
Product 2: Calcined Talc
After calcined, the whiteness can be up to more than 90%, with good insulation, heat resistance, adsorption, lubrication and other properties. If the magnesium oxide in the glaze is introduced with black talc, the glaze surface is not easy to occur rolling phenomenon, which is conducive to the opacification and can increase the whiteness of the glaze.
Product 3: Nepheline
Nepheline syenite is a quartz-free aluminium silicate. It primarily comprises nepheline, microcline and albite. Because of its extremely low melting point and high alumina content, nepheline syenite is used as a flux in ceramics, to lower melting temperatures in glass, and as a functional fller in coatings and polymers.Nepheline Syenite is characterized by high ratio of (Na2O+K2O)/SiO2 and(Na2O+K2O)/Al2O3, which are represented respectively by the existence of nepheline and alkaline mafic minerals. Therefore, it is classifed as MIX FELDSPAR also.
