Long-wavelength absorption of cermets
Physical Review B, 1988Cermets are inhomogeneous materials composed of small metal spheres randomly distributed in a host dielectric. A theory is presented for the electromagnetic absorption at very long wavelength. The most important quantity is the magnetic permeability ..mu.., even for nonmagnetic systems.

1. Grinding of test specimens of porous cermets was accompanied by the appearance in the surface layer of first-order residual tensile stress, reaching 40–100 daN/mm2. 2. The value of the residual stress can be controlled within certain limits by changing the grinding depth, the feed rate and the speed of the table.

This chapter introduces the nano-cermet and nano-cermet inert anode. In order to overcome the shortcomings of cermet inert anode, nano-cermet has been used as inert anode materials. The preparation, characterization, physical properties, conductivity, high-temperature resistance, and high corrosion resistance of nano-cermet are introduced.

Thin Solid Films, 1967
Abstract Details are given of the properties of cermet resistors produced by evaporation of chromium and silicon monoxide. The resistors have been produced over a range of sheet resistances, between 200 and 4,000 ohms/square. The reproducibility of results decreases with increasing sheet resistance and suggests that 2,500 ohms/ square is the maximum ...

On the strength of cermet alloys
Soviet Powder Metallurgy and Metal Ceramics, 1964The results of mechanical tests obtained on alloys of TiC-Co, TiC-Ni, TiC-Mo, close by their nature to the alloy WC-Co at temperatures of 20‡ and 1200‡C, confirm G. S. Kreimer's view that “refractory compoundsmetal” alloys are fragile within wide ranges of change in bond and temperature as opposed to V. A. Ivensen's assertion (Powder Metallurgy No.

Abstract : Several compositions of cermets based on titanium nitride were investigated. The cermets were tested for strength in cross bending, resistance to oxidation, and resistance to thermal shock. The differences of the various compositions are noted as well as the effect of different processing techniques.

IEEE Transactions on Parts, Materials and Packaging, 1967
Both resistive and insulating cermets were obtained from experiments on co-evaporated materials. Stable resistivities in the 1000 micro-ohm-centimeter range were obtained from mixtures of germanium and chromium, and from a reaction product of aluminum and alumina. Glassy dielectric films were obtained from reaction products of aluminum and alumina, and
