Improving the synthesis of metal oxides, reception and study of powder materials using concentrated radiant energy popup.stage_title Head Frolov Gennadiy Alexandrovich, Доктор технічних наук Registration Date 16-02-2018 Organization Frantzevich Insitute for Materials Science Problems of the Ukranian National Academy of Sciences popup.description2 The study of thermerosion stability of UHTC samples and its coatings on carbon-carbon substrates up to 1830 oC were tested. Samples of NiCr and Nb based alloys under conditions of convective heating at a surface temperature of 1200 °C. The high efficiency of these alloys due to the formation of protective films on the surface is established. Investigations of influence of impurities on the formation of fine and nanodispersed materials and coatings on the basis of composite nitrides have been carried out. It is established that the thermal conductivity of cellular structures samples of practically does not change at pressure less than 10-3 mm Hg. Experimental data describing the main stages of the transformation of tungsten-copper pseudoalloy in an oxidizing environment are obtained. They will be useful for developing technology for the recovery of tungsten from materials that contain tungsten. Product Description popup.authors І. Нешпор І. Подчерняєва А. Панасюк А.
