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.).
