Preparation and Heat Resistance of Porous Titanium Carbosilicide

The results of studies on the preparation of titanium carbosilicide with porosities of 20, 40, and 60% are presented. Experimental samples were obtained using a pore former in the form of NaCl crystals. Sintering of porous samples at temperatures up to 1300°C was characterized using thermomechanical...

Description
Summary:The results of studies on the preparation of titanium carbosilicide with porosities of 20, 40, and 60% are presented. Experimental samples were obtained using a pore former in the form of NaCl crystals. Sintering of porous samples at temperatures up to 1300°C was characterized using thermomechanical analysis. The pore structure was studied at the macro- and micro-levels using the method of optical microscopy. The nature of the oxidation of the studied samples was revealed based on mass change with the duration of tests and intensity of corrosion in air at 1100°C. X-ray diffraction analysis and Raman spectroscopy results showed that during high-temperature oxidation, predominantly titanium oxide is formed in the form of rutile.
