Latest Patents

Makino's latest patents focus on the method of producing spherical calcium carbonate. The process involves blowing carbon dioxide gas into an aqueous suspension containing calcium hydroxide. After the reaction begins, a water-soluble phosphoric acid compound is added when the carbonation ratio reaches 2 to 10%. The reaction continues at a low gas blowing rate, allowing for the production of spherical calcium carbonate with a mean particle diameter of 10 µm or larger. This method results in calcite-type spherical calcium carbonate that exhibits high brightness and a small friction coefficient, closely resembling a true sphere.
