CERAMIC BINDER OF HIGH-PRESSURE STEAM CURING AND METHOD FOR PRODUCTION OF CERAMIC MATERIALS USING THE SAME Russian patent published in 2005 - IPC

FIELD: ceramic binder and ceramic materials made from the same.

SUBSTANCE: ceramic binder is obtained by thermal treatment of raw materials containing (mass %) clay (e.g., clay waste) 20-45; limestone (e.g., limestone waste) 5-30; and ash (e.g., ash from thermoelectric plant) 25-75, at 900-1150⁰C. Method for production of ceramic materials using the claimed binder includes mixing of raw materials, forming, and thermal treatment at 174-210⁰C under pressure of 0.8-1.6 MN/m² in saturated water steam.

EFFECT: low-cost ceramic materials with reduced volume weight and high mechanical strength.
