Latest Patents
Hideo Yamada holds a patent for a "Method for the preparation of acid-resistant calcium silicate." This novel method involves a hydrothermal reaction of a blend of silica-containing material and calcium oxide or hydroxide under specific conditions. The resulting calcium silicate powder exhibits extremely high acid resistance, making it particularly useful as a filter aid in the filtration of acidic aqueous liquids. The method also includes a heat treatment step at temperatures ranging from 800°C to 1200°C for a duration of 0.5 to 2 hours. An improvement in the clarity of the filtrate is achieved when the hydrothermal reaction is conducted in an aqueous solution of potassium hydroxide at a specified concentration.
