Applications

Zinc powder is used in thermal spraying for corrosion protection and in the chemical industry. It provides chemical potential energy in alkaline batteries to pump electrical charges between the negative and positive terminals. It is used as a fuel for model rockets with a mixture of 2.04 parts zinc to one part sulfur. It is used as protective pigment in industrial coatings, as a reducing agent and catalyst in a variety of chemical reactions.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store under dry inert gas. It is sensitive to air and moisture. Incompatible with strong acids, strong bases and oxidizing agents.
