![]() ![]() ![]() chrome oxide green also serves as starting material for the preparation of fire resistant materials used inter alia for lining melting furnaces or vats, e.g.Because of its deep green color, it takes up an important place among inorganic pigments. It is a pigment with high coloring and covering power which is thermally and mechanically stale up to high temperatures and inert towards most chemicals. the oxide of trivalent chromium which crystallizes in the corundum latice has long been known.Chrome oxide green is an important inorganic pigment.This invention relates to improved chrome oxide green, to a process for its preparation and to its use.C01P2006/82- Compositional purity water content.C01P2006/00- Physical properties of inorganic compounds.C01P2004/60- Particles characterised by their size.C01P- INDEXING SCHEME RELATING TO STRUCTURAL AND PHYSICAL ASPECTS OF SOLID INORGANIC COMPOUNDS.C09C1/00- Treatment of specific inorganic materials other than fibrous fillers Preparation of carbon black.C09C- TREATMENT OF INORGANIC MATERIALS, OTHER THAN FIBROUS FILLERS, TO ENHANCE THEIR PIGMENTING OR FILLING PROPERTIES PREPARATION OF CARBON BLACK PREPARATION OF INORGANIC MATERIALS WHICH ARE NO SINGLE CHEMICAL COMPOUNDS AND WHICH ARE MAINLY USED AS PIGMENTS OR FILLERS.C09- DYES PAINTS POLISHES NATURAL RESINS ADHESIVES COMPOSITIONS NOT OTHERWISE PROVIDED FOR APPLICATIONS OF MATERIALS NOT OTHERWISE PROVIDED FOR.C01B32/914- Carbides of single elements. ![]() C01B- NON-METALLIC ELEMENTS COMPOUNDS THEREOF METALLOIDS OR COMPOUNDS THEREOF NOT COVERED BY SUBCLASS C01C.C22B34/30- Obtaining chromium, molybdenum or tungsten.C22B- PRODUCTION AND REFINING OF METALS PRETREATMENT OF RAW MATERIALS.C22- METALLURGY FERROUS OR NON-FERROUS ALLOYS TREATMENT OF ALLOYS OR NON-FERROUS METALS.Assignors: HOFS, HANS-ULRICH, RADE, DIETER, RADEMACHERS, JAKOB, TEICHMANN, GUNTHER, TRENCZEK, GERHARD Application granted granted Critical Publication of US4957562A publication Critical patent/US4957562A/en Anticipated expiration legal-status Critical Status Expired - Lifetime legal-status Critical Current Links OF GERMANY ASSIGNMENT OF ASSIGNORS INTEREST.
