摘要
The present invention relates to a method for producing a water-3N4A slurry-like Si-based composition for producing ceramics, and a low-cost, compact and high-strength Si3N4And a sintering aid of 0.2 to 7.5% by weight in terms of oxide, 0.05 to 10% by weight of a sintering aid, To 3% by weight of a dispersant and the pH of which is adjusted to 8 to 12, and the Si powder and the Si powder are obtained by oxidizing commercially available Si powder at 200 to 800C in the atmosphere , And Si of the Si group L composition3N4And the sintered body has a relative density of 95% or more and an anti-seizing strength of 800 MPa or more.
