The possibility of using waste of semiconductor manufacturing containing silicon carbide and gallium arsenide as an effective additive in radio absorbing material preparation was established as a result of research. The resulting material meets the requirements of effective porous electromagnetic radiation absorbers of extremely high frequency range: maximum absorption and minimum reflection of electromagnetic radiation, fire safety, the minimum allowable level of toxic and hazardous substances.

Biocoatings were formed on the surface of the Mg0.8Ca alloy by the method of micro-arc oxidation, in an electrolyte containing β-Ca3(PO4)2 (β-TCP) and CaSiO3, When the process voltage was varied in the range of 350–500 V, the thickness, roughness, and mass of the coatings increased to the values of 110 µm, 12 µm, and 11 mg, respectively. The presence of the following crystalline phases was determined in the coatings: α-TCP, wollastonite, forsterite and magnesium oxide. Coatings containing these compounds not only reduce the rate of bioresorption of the magnesium alloy, but also promote the process of bone tissue formation.
