| titleOfInvention | Manufacturing method of high wear resistant silicon nitride (Si_3N_4) sintered body |
| abstract | The present invention relates to a method for producing a silicon nitride sintered body having high wear resistance with easy formation of alpha phase and compact structure of the sintered body by controlling the amount of the sintering aid added to the silicon nitride powder and controlling the sintering atmosphere gas pressure in two stages.n n n The present invention is a method for producing a silicon nitride sintered body, by adding a sintering aid to the silicon nitride powder in 4-10% by weight to make a molded body, the molded body is nitrogen gas pressure in the temperature range of 1600-1800 ℃ without using a powder bed After the first sintering for 10-30 minutes to have a sintered density of 95% at 2-5 atm, and then sintered for 30-4 hours at 50-100 atm to have a sintered density of at least 95%. The summary relates to a method for producing a silicon nitride sintered body having high wear resistance. |
