SYNTHETIC WOLLASTONITE AND METHOD OF PREPARATION THEREOF Russian patent published in 2002 - IPC

Abstract RU 2181105 C1

FIELD: composite materials. SUBSTANCE: invention relates to preparing silicates employed as modifying fillers for composite materials in chemical industry (varnishes, paints, rubber, etc.) as well as effective substitutes for natural-origin finishing stones. Invention, in particular, provides wollastonite containing, wt %: silica 60.0-66.0, calcium oxide 27,2-33.4, sodium oxide 5.5-6.5, and alumina 0.1-0.3. For preparation of blend containing silica and components based on sodium carbonate and calcium oxide, waste from separation stage of calcium carbide production process is used, in particular calcium carbonate/calcium oxide/calcium hydroxide mix (38:11: 2). Resulting blend is melted at 1380-1390 C for 1.0-1.5 h, molded, and crystallized at 1050-1070 C for 15 to 20 min. Product is characterized by stable needle habitus wollastonite modification. EFFECT: intensified process and reduced cost price of produce. 2 cl, 1 tbl
