How about the water content of Zinc Oxide in indirect method?
Different raw materials to produce zinc, the purity of Zinc Oxide is not the same, the main production process of 99.5%--99.7% Zinc Oxide.
The indirect method of Zinc Oxide standard GB/T3185-92, raw material except zinc ingots, the main raw materials for the production of zinc slag is the indirect method of Zinc Oxide. Well, Zinc Oxide pure zinc process, content production can reach more than 99.8%.
The indirect method with zinc ingots as raw material, zinc in high temperature graphite crucible at 1000 DEG C converted to zinc vapor, air oxidation of Zinc Oxide before being fed into, and Zinc Oxide collected particles in the cooling tube.
