Composite Stable to Corrosive Media in SiC-AL2O3-Si2ON2 System
Abstract: The object of the research was to study the composite received in impure nitrogen medium from silicon carbide, silicon and refractory clay mixture. With X-ray diffraction, petrographic and electron microscope methods the chemical processes happening at burning of the mentioned mixture in technical nitrogen medium and the kind of received binder, phase composition and basic properties are studied. It is stated that silicon carbide composite with complex binder is received, the main phases being: Si2ON2, 3Al2O2SiO2 and SiO2. SiC-Al2O3 composite is also received and studied. Water and acid resistance of composites (H2SO4, r—1.84 g/sm3) and resistance to nonferrous metals and slag are studied. The received composites can be used for production of protective envelope of thermocouple for measuring of temperature of ferrous and nonferrous metals at high temperatures.
