SARA Zinc Ash Dust, Purity : 90%, 32% - 45%

A grayish colored powder. May produce toxic zinc oxide fumes when heated to very high temperatures or when burned. Insoluble in water. Used in paints, bleaches and to make other chemicals.Crude zinc ashes (also called zinc skimmings) are the residues left behind in the galvanising bath after the hot dip galvanising of steel. The zinc ashes appear as a thin layer on the surface of the galvanising bath, and are removed after each cycleZinc Ash is also known as zinc dust, chemical formula: Zn. Usage:Zinc ash is mainly used for refining of metal zinc or zinc salts as well as the synthesis of other synthetic chemical fertilizers etc.Zinc ash is generated as dross at the surface of molten zinc bath during galvanization processes of steel pipes and sheets. The weight percentage of it amounts to 12-1 5% to the total amount of zinc metal used for galvanization. It is skimmed manually from the surface of the galvanizing bath and keeping in iron tanks
