A natural diopside CaMgSi2O6 was formed by plasma spray technique into coatings on magnesium substrates as well as self-standing plates. The powder for spraying came from as-mined natural diopside and was crushed and sieved to the proper size for plasma spraying by a water-stabilized plasma torch (WSP). By removing the substrates after cooling, self-supporting plates were obtained. These deposits as well as thinner coatings on Mg alloy were studied with optical microscopy, SEM, X-ray diffraction, thermal analysis, mechanical tests and dielectric spectroscopyMicrohardness was measured on cross-sections prepared for microstructure observation. Wear resistance at wet conditions was tested as well. Dielectric properties of monoblock capacitors prepared from the self standing deposits were measured at low voltage. The results showed that diopside is interesting candidate for various electrical applications; it has similar dielectric behavior as alumina or silicates. The differences
