The microwave properties of numerous perovskite antimonates like A,MeSbO,where A&equals;Ba or Sr, Me&equals;a rare earth, Y, Sc, Ga, or In and A,MeSb,O,where A&equals;Ba or Sr and M&equals;Li, Na or K were measured at 10 Ghz and 300 K. Using the microwave properties and lattice parameters of these materials, the Clausius-Mossotti relationship and a nonlinear regression fitting program, the polarizability of Sb,was investigated and determined to be 1.18&plusmn;0.49 A,. This low polarizability and the low loss of antimonates in general indicate that Sb,is an excellent candidate for use as a constituent in the fabrication of low dielectric constant, low loss, lattice matching perovskite oxide microwave substrates.

Rare earth magnet alloys are comminuted into fine particles at room tempeure up to about 400.degree. C. by placing the alloy into a vessel and pressurizing the vessel, hydriding the alloy, depressurizing the alloy to atmospheric pressure after the absorption of hydrogen and evacuating the vessel so that the absorbed hydrogen is given up leaving microfissures in the alloy, and comminution of the sample.

Method of comminuting rare earth magnet alloys into fine particles

A method is disclosed of operating a cold-cathode-cold-reservoir thyratron for laser/radar and other systems employing high voltage and current pulses using ZrVFe as the hydrogen thyratron material. According to the method, a hydride of ZrVFe is first formed and the hydrided material then placed in the cathode structure of the thyratron. The tube is then pumped down to its operating pressure of approximately 10.sup.-3 atmospheres, the hydrided material then acting as a ballast to maintain that partial pressure of hydrogen at room temperature.
