Information × Registration Number 0201U005014, 0193U017358 , R & D reports Title The study of synthesis mechanism for refractory compounds in chemical reactions with different degree of gas phase participation with the aim of the creation of processing to obtain the high fine-particles powders and materials with given properties popup.stage_title Head Koval'chenko Mykhajlo Savych, Registration Date 15-05-2001 Organization Frantzevich Insitute for Materials Science Problems of the Ukranian National Academy of Sciences popup.description2 The effects of purity, particles size, crystal structure of starting components, gas media as well as catalitic additions on kinetics and mechanism of synthesis for boron, silicon, and aluminium nitrides, nickel boride, boron, molybdenum and tungsten silicides of elements, formation of composite materials in the system of titanium nitrides with aluminium and silicon nitrides, boron carbide with iron, cobalt and nickel borides, binary aluminium-based boride phases, boron suboxide, silicon carbide with chromium-containing surface layer are studied. On the base of results obtained the scientific approach is determined to the control in synthesis of the refractory compounds above, and original processing for fadbricating the grindless powders with redulated particle size and morphology is developed. Processing properties of synthesized powders during forming, sintering, hot pressing, and thermomechanical treatment for materials on the base of the powders above are studied.
