发明名称 GEMISCHTE CHROM(III) OXYDPASTE FUER DIE CHROMDIOXYDSYNTHESE.
摘要 Chromic acid and inexpensive, coarse grained Cr2O3 are dissolved in water prior to adding more costly fine grained Cr2O3 to produce chrome pastes which are more economical than pastes prepared by prior art techniques employing only fine grained Cr2O3. The pastes are equivalent to prior art pastes when reacted to form chromium dioxide.
