在石墨坩埚运用中,因为金属含量不同(30-90%),烧结温度也不同。金属含量较低的石墨坩埚,*要靠粘结剂焦化联结。金属粉末不能构成网状结构,但参加导电。那么,石墨坩埚是怎么进行真空烧结的呢?辉县市金镶玉石墨模具制品山东彩票来为大家解析。

石墨坩埚的热加工进程称为烧结。压坯中的金属粉末,在烧结进程中,因为高温效果,金属原子的振幅加大,经过粘性活动、蒸发与凝聚、体积分散、表面分散、晶界分散、塑性活动等效果,使接触面上有山东彩票的原子进入原子效果力的范围,构成粘结面,导致再结晶与晶粒长大,构成金属网状结构体,使烧结体的强度添加、电阻下降。石墨坩埚的烧结属互不熔系固相烧结。(相关阅读:如何挑选石墨坩埚的材料)
