Measurements
The resultant powder is then die pressed into a component. This component is then sintered at 1200 °C in a furnace.
The ferrites are mostly available in discs, blocks and rings. The temperature range in which it acts normally is from - 40°C to +250°C. But it has a poor temperature coefficient and hence when heated above zero, it loses 0.2% of remanence per 00C.
The Ferrite which is sintered will not corrode in salt water applications. The ferrite magnets have good chemical stability, concentrated acid like hydrochloric acid being the only exception.
The mechanical properties of the ferrite magnet are similar to ceramics or porcelain which means that grinding techniques can be used for these products. A great deal of care is required during handling because of their brittle nature.
