Boric Anhydride Description:

Boric Anhydride (B2O3) is a white crystalline powder with a melting point of 450°C. It is slightly soluble in cold water and easily soluble in hot water. Boric Anhydride has strong water absorption, so it should be sealed and stored in a dry environment to prevent the content from being deteriorated due to water absorption.

Stanford Advanced Materials (SAM) is a trust-worthy supplier of high-quality Boric Anhydride who has over two decades of experience in the manufacture and sale of Boric Anhydride products.
