Sulfidation and reduction of zinc titanate and zinc oxide

The sulfidation reaction kinetics of fine particles of zinc titanate and zinc oxide with H{sub 2}S were studied in order to test the potential of the sorbent injection hot-gas desulfurization process. Fine sorbent particles with diameter between 0.3 and 60 {mu}m were sulfided with H{sub 2}S and/or reduced with H{sub 2} in a laminar flow reactor over the temperature range of 500-900{degrees}C Get price

ZINC DUST

Zinc powder reacts explosively when heated with manganese chloride. The reaction between zinc and selenium or tellurium is accompanied by incandescence [Mellor 4:476-480 1946-47]. When zinc and ammonium nitrate are mixed and wetted with a minimum of water, a violent reaction occurs with evolution of steam and zinc oxide. Get price

Raw Materials Dictionary / Ceramics Glaze making, Clay

ZINC OXIDE - ZnO (m.p. 3272o F/1800o C) is derived from Zinc Sulfide ores. It is an important component of many glaze types (cone 5-13) and is used as a flux, opacifier, and color modifier. It reduces the expansion of a glaze (second only to Magnesia), improves craze resistance, gloss, whiteness, and increases maturing range. Get price

Fire retardant finish of jute fabric with nano zinc oxide

Nano zinc oxide (ZnO) was applied on bleached jute fabric to impart fire retardant finish. Nano zinc oxide was prepared from aqueous Zinc acetate by co-precipitation method in the presence of NaOH followed by calcination at 600nbsp;C. It was then applied on the jute fabric using an aqueous solution of Potassium Methyl Siliconate as dispersing media by pad-dry method. Among different dosages Get price

Zircon

Tin oxide, by contrast can produce more of a blue-white, but tin is subject to alteration of the color (toward pink) if there is any chrome in the kiln atmosphere (zircon is unaffected by this). If the shade of white is too harsh, it can be toned by shifting part of the opacification burden to tin or by adding a tiny amount of stain (e.g. blue, brown, grey). Get price
