 note = {Two kinds of SiC powders (A and B) were synthesized from mixtures of Shirasu glass and carbon black heated at 1650°C and 1900°C in a vacuum (0.1mmHg). The SiC powders and additives such as Al(2%), AL(2%)+B(2%)+C(2%) or AIN(2%)+B(2%)+C(2%) were hot-pressed under a pressure of 400Kg/cm^2 at 1900°C for 30min. The relative density of the most densified specimen by hot-pressing was 99%. The hot-pressed specimens were tested on bending strength, Vickers hardness, acid durability, alkaline durability and oxidation resistance. The results obtained on the specimens having relative densities > 97% are as follows: The bending strength was 55-60kg/mm^2 and the Vickers hardness was 2700-3000kg/mm^2. In both the acid (12N Hcl) and the alkaline (6N NaOH) durability tests at 80°C, the values of weight loss were 0.1-0.2wt%. In oxidation resistance tests (in air) at 1400°C, values of weight gain were 1.0-1.5mg/cm^2.},
