METHOD OF OBTAINING WOLLASTONITE-BASED CERAMIC PRODUCTS Russian patent published in 2009 - IPC C04B33/28 C04B35/80 C04B35/16

Abstract RU 2365559 C2

FIELD: chemistry.

SUBSTANCE: invention relates to technology of manufacturing constructional ceramic elements of accessories of aluminium industry founding units. Claimed method includes preparing of water slip by simultaneous milling of natural wollastonite, kaolin, clay with addition of water, liquid glass and calcined soda, formation of products, drying and burning. In slip additionally introduced is 3-15 mm long silica-alumina fibre in amount 5.0-10.0% of slip weight. Formation of products is realised by method of slip casting into porous forms.

EFFECT: expansion of assortment of constructional products based on natural wollastonite for aluminium industry, which have increased heat resistance and increased operation resource, as well as essential reduction of aluminium bar contamination with ceramic inclusions.
