Industrial Uses

1. Construction

  • Concrete additive: Lithium metasilicate is used in construction primarily as a concrete additive and surface treatment. It enhances concrete's durability, strength, and resistance to chemical attack, while also reducing issues like alkali-silica reaction and efflorescence. Additionally, it's used in refractory materials and as a coating for concrete, masonry, and metal surfaces.

2. Performance Chemicals

  • Biodiesel Production: Lithium metasilicate has been successfully used as a heterogeneous catalyst for the transesterification of soybean oil to produce biodiesel. It can achieve high biodiesel yields, even with high acid values in the oil. The catalyst can be recycled and reused, making it a cost-effective option.
  • Hydrothermal synthesis: This method involves reacting lithium and silicon-containing precursors in an aqueous solution under specific temperature and pressure conditions. 
  • Solid-state reaction: This involves mixing lithium and silicon-containing compounds and heating them to form lithium metasilicate. 
  • Microwave-assisted hydrothermal synthesis: This method utilizes microwave irradiation to accelerate the reaction and can produce Li2SiO3 with specific morphologies and surface areas.
