Function and Use
1. Electronics Industry: Essential for producing soft ferrites used as magnetic cores, disks, and tapes. It is widely applied in electronic computers, telephone transformers, commodity inductors, TV return transformers, magnetic heads, and antenna rods. It also serves as a specialized pigment for paints and coatings.
2. Specialized Manufacturing: Used in the production of optical glass and low-temperature thermistors.
Package, Storage and Transportation
Store in a cool, ventilated warehouse. Keep strictly away from fire and heat sources while avoiding direct sunlight. Ensure the package is tightly sealed. It must be stored separately from hydrochloric acid and edible chemicals. Storage areas should be prepared with appropriate containment materials for potential leaks.
Physical and Chemical Properties
Manganese tetraoxide is a black tetragonal crystalline oxide, which is toxic and crystallizes after burning. It is insoluble in water but soluble in concentrated hydrochloric acid and concentrated sulfuric acid.
