White crystalline powder. For the mixture of zinc sulfide and barium sulfate, the more zinc sulfide, the stronger the hiding power, the higher the quality. Density 4.136~4.34 g/cm3, insoluble in water. When the acid is easily decomposed to produce hydrogen sulfide gas, hydrogen sulfide and alkali solution does not work. Ultraviolet light from the sun into the 6~7h into a light gray, in the dark still restore the original color. Easy oxidation in the air, after the deterioration of moisture caking.
