An Púdar Zno Indíreach Indíreach agus an púdar directZnO

There are directZnO powder and indirectZnO powderfor the production of zinc oxide. The difference between indirectZnO powder and directZnO powder is that their manufacturing materials and processes are different, so the fields of application are also different.

1. Púdar DirectZno

DirectZnO powdermostly uses zinc ore, zinc ash, and zinc concentrate as raw materials, which are oxidized and roasted at high temperature and then reduced to zinc vapor by adding coal.

The zinc vapor is oxidized with hot air to obtain Direct ZnO powder. The product purity of this process is low, generally between 75% and 95%, with high or low impurity content.

2. Púdar indíreach ZnO

The raw material of indirectZnO powder is metal zinc ingots or zinc slag obtained by smelting. It is a white hexagonal crystal or powder at room temperature with a particle size of about 0.1-10 microns. Hardly soluble in water, soluble in acid and strong alkali, ammonia and ammonium salt solution. It is odorless, tasteless and sandless. It turns yellow when heated, and turns white again after cooling, and sublimates when heated to 1800°C.
