Globular graphite in the catalyzer during making artificial diamond 人造金刚石熔媒中的球状石墨
Graphite smelting and solidifying in arc furnace is in globular shape, and homogeneous globular graphite is achieved in rapidly-solidified alloy prepared by 3m drop tube. 在电弧炉中熔炼并凝固,石墨基本呈球状组织形态,在3m落管中经深过冷快速凝固后石墨呈球状组织。
