Zinc Powder Used Specially for Chemical Reducing Agent

Sample Nature:

Molecular formula:Zn

Molecular weight:65.38

Physical property:Dark gray metal fine powder.

Density :7.14g/cm³, Melting point: 419.58℃，

Boiling point: 907℃.

Chemical Properties:

It does not dissolve in water. It dissolves in acid and base. It dissolves in acetic acid and ammonia water slowly. It has strong reducibility. When it reacts with acid and base, hydrogen will be produced. It agglomerates under humid condition. It is stable in dry air. White basic carbonate is produced in humid air and it covers on the surface. When it is burnt in air, blue flame is produced. Besides, zinc oxide is generated. The product with high purity reacts with sulfuric acid, nitric acid and hydrochloric acid slowly. When it contains a little other metal such as iron, tin and lead, the reaction will accelerate.

Product Characteristics:

Huiyuan zinc powder used specially for chemical reducing agent has characteristics such as high metal zinc content, low content of other impurity elements, smooth particle surface and large

specific surface area,low loose-packed powder density, less surface oxidation and less melting deformation and grape-like particles through adhesion. Total zinc content is more than 98.5% and

metal zinc content is more than 96%.

Product Use:

Huiyuan zinc powder used specially for chemical reducing agent is used for organic, inorganic

chemical industry, medicine, pesticide, printing and dyeing, reducing agent and catalyst industry.

In terms of chemical production, it is used for production of sodium hydrosulfite, lithopone, sodium formaldehyde su lfoxylate, zinc sulfate and zinc chloride and impurity removal.
