在同一件条下,曾吹入不同量的其它气体(Ar,N2)等,但并没有任何球墨痕迹。问题很明显,因为吹这些气体不能产生与式(4)相同的物理化学过程。得出的石墨,如很多研究家所提到过的——过冷石墨。多次试验说明,在上述条件下不能得到100%球状石墨,原因是,当CH4在石英管中通过炉中之中温区(约800℃)时,已部分分解,分解的产物H2和石墨同时进入液态铸铁,宛如用氢气往铸跌里吹石墨一样。如此,吹入之石墨成为生成片状石墨的晶核。当把石英吹管吹口之直径缩小到0．3公厘时,在开始吹的时候,还没有什么特别感
Under the same article, different amounts of other gases (Ar, N2), etc. were blown in, but there was no trace of ductile ink. The problem is obvious because blowing these gases does not produce the same physicochemical processes as in equation (4). The resulting graphite, as many researchers have mentioned - supercooled graphite. A number of tests have shown that 100% spherical graphite can not be obtained under the above conditions because CH4 partially decomposed when passed in a quartz tube through a medium temperature zone in a furnace (about 800C), and the decomposed product H2 and graphite simultaneously enter Liquid cast iron, like a drop of graphite with hydrogen gas down to the same. In this way, the blown graphite becomes a nucleus for generating flaky graphite. When the diameter of the mouthpiece of the quartz blow pipe is reduced to 0.3 mm, there is no special feeling at the beginning of blowing
