Zinc Oxide(Indirect Method), Brand Name : Swallow

Zinc oxide (zno), commonly known as zinc white, is a kind of oxide of zinc, which is insoluble in water but soluble in acid and alkali. Zinc oxide(indirect method) is the use of zinc ingots as raw materials, which is conversed to zinc vapor in graphite crucible at 1000 â° c, then zinc vapor is oxidized by bubbling air and through the cooling tube, zinc oxide particles are collected. The product purity varies with the raw material of zinc ingots. Except zinc ingots, zinc slag is another kind of raw material. Good technology and pure zinc ingots can make the product purity reach more than 99.8%.
