Zinc oxide powder basic data:

The MST® French process zinc oxide powder can use low-spec zinc-containing raw materials such as zinc slag, but it needs to use gas-liquid separation technology to separate impurities such as Cd, Pb, Fe and Al in advance to improve the purity of the zinc vapor. The measures to remove impurities are as follows:

1) Using crucible method or muffle furnace method to slag and separate impurities such as Fe and Pb that are not easy to evaporate.

2) Fractional distillation is used to separate impurities such as Cd, Pb, Fe, Al and Cu in the high-temperature vaporized raw material vapor when passing through a fractionating tray made of silicon carbide material.

3) Using the two-chamber furnace separation method, the raw materials are separated from impurities in the one-chamber furnace in advance, and after entering the second chamber, they are distilled in the absence of oxygen to improve the purity of the zinc vapor. Fractional distillation separates a small amount of Pb.

4) Using the rotary kiln method, the material is melted, distilled, and partially oxidized in the rotary kiln. The operating conditions such as temperature, CO2 and O2 partial pressure can be controlled to reduce the content of Pb impurities, and the French process can also be controlled. The particle and crystal shape of zinc oxide.

The MST® French process zinc oxide powder produced by MST is made with the best grade 0# zinc ingot, which can ensure that the heavy metal content is low in the Buy French process zinc oxide powder

And MST uses its own proprietary technology in the production of MST® French process zinc oxide powder , which will make the quality of Buy French process zinc oxide powder higher.
