How is Calcium oxosilanediolate (CAS: 10101-39-0) typically synthesized?

Calcium oxosilanediolate (CAS: 10101-39-0) is typically synthesized through a reaction between calcium oxide, silica, and water. The process involves mixing calcium oxide and silica in a molar ratio, followed by the addition of water and subsequent heating. Common catalysts used include hydrochloric acid or other acidic solutions to enhance the reaction rate and selectivity. The yield of the product is approximately 85-90%.
