...-mutual shells structured pigments were prepared for improving the corrosion resistivity of the organic coatings as a new trend in anticorrosive pigments. A reversal process was performed through the dispersion of silica fume in an iron soluble salt solution with adequate quantity of distilled water...

...) with different ratios of silica fume and meta-kaolin and applying two paint formulations to enhance corrosion resistance and mechanical properties. In this work, modified concrete mixes containing pozzolanic materials of industrial wastes such as silica fume (SF) with ratios ranging between (0, 10 and 15...

...Nivin M. Ahmed; Mostafa G. Mohamed; Reham H. Tammam; Mohamed R. Mabrouk Purpose This study aims to apply novel anticorrosive pigments containing silica fume-phosphates (Si-Ph), which were prepared using core-shell technique by covering 80-90 per cent silica fume (core) with 10-20 per cent...

.... The colour strength, thermal stability, mobility, aqueous dispersability and ultraviolet (UV) resistance of modified pigments were studied. Design/methodology/approach Silica fume was added into the diazonium salt solution under acidic condition, followed by the activation to generate new surface...

...Nivin M. Ahmed; Walaa M. Abd El-Gawad; Elham A. Youssef; Eglal M. Souaya Purpose – The purpose of this work is to prepare new core-shell pigments based on silca fume waste as core and ferrite pigments in the shell. Silica fume is a byproduct of the smelting process in the ferrosilicon industry...
