Latest Patents

Lasmarias holds a patent for a "Method for preparing acid resistant calcium carbonate pigments." This method involves creating an aqueous slurry of particulate calcium carbonate at a pH of approximately 11.0 to 12.0, with an excess of calcium hydroxide. The process includes heating the slurry to a temperature range of about 75 to 80 degrees Celsius and gradually mixing in sodium silicate solution. The addition of gaseous carbon dioxide adjusts the pH to between 10.2 and 10.7, followed by cooling the slurry and incorporating zinc chloride to achieve a final pH of 7.5 to 8.0. This innovative method results in a pigment that is resistant to acidic conditions.
