Lead bisilicate is a widely used inorganic lead silicate material mainly applied in ceramic, glass and enamel industries. It acts as an effective low-temperature flux to reduce the melting point of glazes and raw glass materials, improving fluidity, surface gloss and processing performance during production. In ceramic colorants and glazes, it stabilizes pigments, enhances color development and improves weather resistance of finished products. It is also an important additive for enamel coatings, significantly boosting adhesion, acid and alkali resistance of coating layers. Besides traditional building materials, this compound is used in electronic glass, sealing glass and welding glass production, and serves as a carrier for some industrial catalysts. Due to its lead-containing property, it is strictly restricted to industrial material fields and prohibited from being used in food, pharmaceuticals, cosmetics and medical implants. With stable physical and chemical properties, it remains an essential auxiliary material in modern inorganic non-metallic material manufacturing.

This substance is classified as GHS05 Danger and GHS07 Warning. It is corrosive and toxic. Inhalation of fine dust will severely irritate respiratory tract, causing cough, chest pain and breathing discomfort. Direct skin contact leads to severe irritation, chemical burns and long-term cumulative lead poisoning. Eye contact results in serious corneal damage and even permanent visual impairment. Accidental ingestion causes acute gastrointestinal disorders, and repeated exposure will damage nervous system, blood system and internal organs. All operations must be carried out in well-ventilated fume hoods. Wear chemical-resistant gloves, safety goggles and dust respirator. Never eat, drink or smoke in working areas. In case of skin contact, remove contaminated clothes and rinse skin with plenty of running water for 15 minutes. If dust enters eyes, flush continuously with clean water and seek immediate medical treatment. Do not induce vomiting if swallowed, drink large amounts of water and send to hospital promptly. Store and transport it separately from strong acids and food. Dispose of waste strictly in accordance with local hazardous waste regulations.
