What is Sodium metasilicate？

Sodium metasilicate is white powder with a CAS number of 6834-92-0. It is a common inorganic silicate. The industrial forms include anhydrous, pentahydrate and nonahydrate. Among them, pentahydrate is the most widely used due to its moderate solubility and ease of use. In terms of application, it is an important additive for detergents and serves as a binder for ceramic bodies and a flux for glazes in the ceramic industry. It is also used in metal surface treatment, textile refining and as an early strengthening agent for building concrete, and is an indispensable basic chemical raw material in many industries.
