Function and Use
1
Used in the electronics industry to produce soft ferrites, used as magnetic cores, disks and tapes for storing information in electronic computers, telephone transformers and commodity inductors, TV return transformers, magnetic heads, inductors, magnetic amplifiers, saturated inductors, antenna rods, etc. It can also be used as a pigment for certain paints or coatings.
2
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.
