Product Name: Zinc powder. Classified by production process, standard, content and shape. Materials required: Zinc ingot. Main applications: Used in paints, nano-coatings and surface treatment of precision instruments. Due to its high activity, it is suitable for advanced and special medical fields. Packaging: Iron drum. Annual production: 3000 tons. Note: The provided text contains incomplete information and some parts are not fully translatable due to technical terminology.

Indirect method zinc oxide

Physicochemical Properties of Zinc Oxide White hexagonal crystalline or powder. Tasteless, non-toxic, fine texture. Relative density 5.606. Refractive index 2.008-2.029. Melting point 1975℃. Soluble in acid, sodium hydroxide, and ammonium chloride; insoluble in water, ethanol, and ammonia. It is an amphoteric oxide. It absorbs carbon dioxide and water in the air to form zinc carbonate, appearing yellow. It turns yellow when heated and recovers its white color after cooling. It does not transmit ultraviolet light and does not turn black when exposed to hydrogen sulfide.
