摘要：

This article describes articles made from silicon carbide with an oxynitride bond. The composition is 75. 0% SiC and 5. 3% N//2. The properties are open porosity 19. 0%; apparent density 2. 48 g/cm**3; gas permeability 0. 01 mu m**2; compressive strength 110 MPa; refractoriness under load of 0. 2 MPa, above 1700 degree C; thermal expansion at 1100 degree C 0. 21%, at 1300 degree C 0. 56%; coefficient of thermal expansion 4. 1 multiplied by (times) 10** minus **6 deg C** minus **1; specific heat 1. 17 kJ; thermal conductivity at 500 degree C 11. 6 w/(m multiplied by (times) K), at 1200 degree C 8. 5 w/(m multiplied by (times) K); and thermal-shock resistance (water - 1300 degree C) more than 25 heat cycles.
