Method of protecting Si3N4 ceramic alloy during heating |
| 摘要 |
Articles made from Si3N4 ceramic alloy powders are protected during heating by loosely packing them in Si3N4 before heating. Compacts made from Si3N4 ceramic alloys are protected from both oxidation and from volatilization by the encompassing powder even though the furnace atmosphere is air.
