氧化物碳组份传统上应用于有色金属冶炼及浇注的坩埚工艺之中。碳组份能保证制品的热稳定性、抗金属侵蚀性及抗渣性,而氧化物组份则可保证制品的强度性能。 生产坩埚时,往配料中加入含低灰份及物理性能高度非均质性的天然细小鳞片状石墨,这样就可以选择鳞片状石墨的预期方向,从而可以调整材料的性能及应用范围。此外,此种石墨还可以较少遭到平面氧化,石墨与较少有序的碳相比较,例如与焦炭或灰份相比较,它
Oxide carbon components are traditionally used in crucible processes for smelting and pouring non-ferrous metals. Carbon components to ensure product thermal stability, resistance to metal erosion and slag resistance, while the oxide component can guarantee the strength of the product performance. In the production of crucibles, natural flake-like flake graphite with low ash content and high physical inhomogeneity is added to the batch so that the desired orientation of the flake graphite can be selected so that the material properties and application range can be adjusted. In addition, such graphite may also be less subject to planar oxidation, and graphite is compared to less ordered carbon, for example, as compared to coke or ash
