Employment of new modified ferrite pigments in anticorrosive alkyd-based paints

摘要: Purpose – The purpose of this work is to prepare new core-shell pigments based on silca fume waste as core and ferrite in the shell. Silica a byproduct smelting process ferrosilicon industry. reduction high-purity quartz silicon at temperatures up 2,000°C produces SiO2 vapours which then oxidize condense low-temperature zones tonnage amounts tiny particles consisting non-crystalline silica that collected sold rather than being land-filled because nowadays there increasing environmental concern with regard excessive volumes solid hazards accumulation. has no direct effect protecting metals from corrosion, but precipitating an effective anticorrosive pigment like its surface low concentrations, can bring out good performance cost. will be constructed comprising 80-85 per cent chemical structur...
