Function and Use
- Electronics Industry: Used to produce soft ferrites for magnetic cores, disks, and tapes. Essential for electronic computers, telephone transformers, commodity inductors, and TV return transformers.
- Magnetic Components: Applied in magnetic heads, inductors, magnetic amplifiers, saturated inductors, and antenna rods.
- Coatings: Serves as a pigment for specific paints or industrial coatings.
- Specialized Glass: Used in the manufacture of optical glass and low-temperature thermistors.
Package, Storage and Transportation
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Avoid direct sunlight. Package tightly. Store separately from hydrochloric acid and edible chemicals. Do not store together. The storage area should be equipped with appropriate materials to contain leaks.
Frequently Asked Questions
A: It is a black tetragonal crystalline oxide. It is known to be toxic, insoluble in water, but can be dissolved in concentrated hydrochloric or sulfuric acids.
A: It is primarily used in the electronics industry for producing soft ferrites (magnetic cores, inductors), optical glass manufacture, and as a pigment in certain coatings.
A: The grades differ in their chemical composition and physical properties, such as Manganese (Mn) content (71.56% vs 71.25%) and levels of impurities like Fe2O3 and MgO.
A: It must be kept in a cool, ventilated area away from heat sources and direct sunlight. It should be stored separately from hydrochloric acid and edible chemicals.
A: No, it is insoluble in water. However, it shows solubility in concentrated hydrochloric acid and concentrated sulfuric acid.
A: It is a key component in manufacturing soft ferrites used for storing information in computers, as well as in transformers, magnetic heads, and antenna rods.
