Abstract
A basic zinc chloride particulate matter and a preparation method therefor. The basic zinc chloride particulate matter mainly consists of basic zinc chloride particles. In the basic zinc chloride particulate matter, D10>100 μm, and D95>450 μm. The basic zinc chloride particles do not contain adhesives. The basic zinc chloride particles contained in the basic zinc chloride particulate matter are approximately spherical, and the basic zinc chloride particles with the particle diameter>500 μm in the basic zinc chloride particulate matter accounts for 1% or less of the total mass of the basic zinc chloride particulate matter.
