High Purity Zinc Oxide ZnO powder CAS 1314-23-4,99.9%

Zinc oxide can be described as an oxide or zinc. Its chemical formula is ZnO. It is insoluble when it comes into contact with water. However, it can be soluble in acidic and strong bases. Purity: 99.5%

Pebble size: 20nm - 200nm

Zinc Oxide powder:

Zinc Oxide is an Inorganic Substance, and its chemical formula is ZnO. Water insoluble, acids and strong base soluble.

Zinc oxide is a white powder. The smell is pleasant, and it's tasteless. It turns yellow once heated and then turns back white when cool. The temperature at 1800 can cause it to sublimate. This concealment power is twice that of zinc sulfide or titanium dioxide. Basic lead carbonate has twice the tinting power. Zinc O can be dissolved in ammonia water, concentrated hydroxide bases, ammonia solution, and ammonia salt solutions, but not in water or ethanol.

Zinc oxide is known for its white pigment. Its common name is Zn white. Zinc oxide is not blackened by H2S gas, as ZnS (also white) can be present. ZnO changes gradually from white to light yellow as it heats. When the temperature drops, the yellow will disappear. To make color-changing paints or thermometers, you can mix them with paint. ZnO can be used as a medicine ingredient to make an ointment. ZnO can be used to act as a catalyst. The additive ZnO in many products is cosmetics, food supplements, rubber, rubber, rubber, gum, rubber, glues, sealants, and pigments. It is found naturally in the mineral zinc. However, many zinc oxides can be synthesized.

Since thousands of years ago, zinc oxide has been used in skincare. Zinc oxygen is safe for the skin. You can use it to soothe skin irritations and as a skin product. It's used to create zinc oxide cream and zink oxide diaper cream. Zinc oxide toothpastes are also made with it.

Zinc Oxide ZnO powder Performance:

White powder, hexagonal crystal. Appearance and properties. No smell, no taste, no sand. The substance turns yellow upon heating, then becomes white again on cooling, and finally sublimates at 1800 degrees Celsius. This hiding power is twice that of zinc sulfide or titanium dioxide. Basic lead carbonate is twice as powerful in coloring.

Solubility: It is soluble in ammonia water, concentrated alkali hydroxide, and ammonia salt solution. However, it is insoluble in water or ethanol.

Application of Zinc oxide ZnO powder ：

Rubber products field

Zinc oxide is widely used in the field of rubber products, and it can be used as a vulcanizing agent and active agent of rubber, improving the high-temperature resistance, wear resistance, and aging resistance of rubber. At the same time, zinc oxide can also be used to manufacture high-grade rubber products, such as tires, hoses, rubber shoes, and so on.

Paint field

Zinc oxide is also widely used in the field of coatings, which can be used as pigments, fillers, and preservatives. Zinc oxide has the characteristics of high whiteness, high hiding power, and high adhesion, which makes it widely used in coatings. At the same time, zinc oxide can also be used to manufacture zinc powder for coatings.

Ceramic field

Zinc oxide also has a certain application in the field of ceramics, and it can be used as a component of ceramic glaze to improve the corrosion resistance and beauty of ceramics. At the same time, zinc oxide can also be used in the manufacture of ceramic vessels and crafts.

Chemical reagent field

As an important chemical reagent, zinc oxide is widely used in electroplating, medicine, pesticide, and other fields. For example, in the field of electroplating, zinc oxide can be used as the main raw material in the galvanizing process; In the field of medicine, zinc oxide can be used to manufacture drugs and health products; In the field of pesticides, zinc oxide can be used as pesticide additives and pesticide carriers.

 Production Method Zinc Oxide ZnO Powder ：

Indirect method

The indirect method is one of the main methods of zinc oxide production, and its process includes zinc ingot melting, oxidation, cooling, crushing, and other steps. First, the zinc ingot is heated and melted, and pure oxygen is added to oxidize the zinc ingot to produce zinc oxide dust, which is collected, cooled, and crushed to obtain zinc oxide products. The advantages are a simple process, easy operation, and high product quality.

Direct method

The direct process is a method of directly oxidizing zinc to zinc oxide. The method directly oxidizes zinc ore, zinc powder, and other zinc-containing raw materials to produce zinc oxide dust. The dust is collected, cooled, and crushed to obtain zinc oxide products. The advantage of this method is that it can directly treat low-grade zinc-containing raw materials and does not require the use of a lot of energy and equipment. However, the process of this method is long, the operation is difficult, and the product quality is relatively low.

Pyrolysis method

Pyrolysis is a method of producing zinc oxide by pyrolysis of zinc-containing raw materials at high temperatures. The zinc-containing raw material is mixed with sodium carbonate solution and pyrolyzed at high temperatures to obtain zinc oxide and carbon dioxide. The advantage of this method is that high-grade zinc-containing raw materials can be processed without the need to use a lot of energy and equipment. However, the process of this method is long, the operation is difficult, and the product quality is relatively low.

Electrolytic method

Electrolysis is a method to obtain zinc oxide by electrolysis of raw materials containing zinc. In this method, the raw material containing zinc is put into the electrolytic cell, the appropriate amount of electrolyte is added, and the current is passed to electrolysis to produce zinc oxide and hydrogen. The advantage of this method is that zinc oxide can be extracted directly from zinc-containing raw materials and does not require the use of a lot of energy and equipment. However, the process of this method is long, the operation is difficult, and the product quality is relatively low.

 Zinc Oxide ZnO powder storage condition:
