Nickel spinels, hot-pressed
The hot-pressed Nickel spinels are
characterized by very low porosity and high thermal conductivity of
ferrite article body. They are recommended for use in microstrip
microwave devices as well as high power waveguide ones.

Lithium spinels
Lithium spinels of this group feature low
non-resonant magnetic losses, high remanent flux density, and high Curie
temperature. They are mostly used in non-resonant controlled devices of
low power levels at cm- and mm- wave ranges (phase shifters, switches
etc.).
