真空氣氛燒結(jié)爐是在真空環(huán)境中對被加熱物品進(jìn)行保護(hù)性燒結(jié)的爐子,。不同的材料選擇適宜的氣氛燒結(jié)，有助于燒結(jié)過程，提高制品致密化程度、獲得良好的性能的制品。真空氣氛爐常用的有真空、氫、氧、氮和惰性氣體（如氬）等各種氣氛。例如透明氧化鋁陶瓷可用氫氣氛燒結(jié)，透明鐵電陶瓷宜用氧氣氛燒結(jié)，氮化物陶瓷如氮化鋁等宜用氮?dú)夥諢Y(jié)。有時(shí)為保護(hù)燒結(jié)調(diào)協(xié)也須在保護(hù)氣氛中操作。如鉬絲爐宜通氫，鎢絲爐宜在真空條件下工作。
Vacuum atmosphere sintering furnace is a furnace that conducts protective sintering of heated items in a vacuum environment,. Choosing appropriate atmosphere sintering for different materials is beneficial for the sintering process, improving the degree of densification of products, and obtaining good performance products. Vacuum atmosphere furnaces commonly use various atmospheres such as vacuum, hydrogen, oxygen, nitrogen, and inert gases (such as argon). For example, transparent alumina ceramics can be sintered in a hydrogen atmosphere, transparent ferroelectric ceramics should be sintered in an oxygen atmosphere, and nitride ceramics such as aluminum nitride should be sintered in a nitrogen atmosphere. Sometimes, in order to protect sintering coordination, it is also necessary to operate in a protective atmosphere. If the molybdenum wire furnace is suitable for hydrogen supply, the tungsten wire furnace should work under vacuum conditions.
