Abstract

Corrosion test of gas-pressure sintered silicon nitride with the additions of yittria and alumina was carried out under various testing conditions. As a result compared with specimens sustained in 6N-H₂SO₄ and those placed at the bottom of glass containers, no significant differences were observed in weight and bending strength. Also, there was no distinctive observation in the test at 90°C and boiling sulfuric acid. Silicon nitride was found to be corroded more severely in H₂SO₄ and H₃PO₄ than NaOH and H₂O. In addition, the test in boiling water resulted in strength degradation of the specimens, while weight change was not detected through corrosion. Relationship between bending strength and weight loss indicated that the rapid decrease of the strength has taken place at below 0.1 mg/cm² of weight loss.
