Reactive sintering of ceramics on the base of boron nitride was studied, and the inert filler was given in this paper.
研究了氮化硼陶瓷的反应烧结，给出了所用惰性填料。
Although GF is electrically inert, its presence can increase the effective concentration of the conductive filler by holding up some space, therefore the conductivity of the material increases.
虽然GF为导电惰性填料，但因其加入起到了占位作用，明显提高了导电填料的有效浓度，从而使复合材料的体积电阻率明显降低。
Because TIG welded joints without filler wire always hold low strength and poor formation, tungsten inert gas welding process with filler wire is inevitable.
由于镁合金不填丝的TIG焊接接头强度低，焊缝表面成型不好，所以，镁合金的填丝tig焊接方法不可避免。
