Potassium silicate (commonly known as potassium water glass) is a versatile inorganic material with the molecular formula K₂O₃Si and a molecular weight of 154.28. It appears as a colorless / pale yellow viscous transparent liquid or white powder. It is primarily used in four major fields: building material bonding and corrosion protection, agricultural fertilizer enhancement, industrial manufacturing, and electronic cleaning. Due to its dual silicon and potassium content and strong weather resistance, it is suitable for high-demand applications across multiple industries.
