Uses include the manufacture of graphite lubricant or pencil refills and pantograph collector strip brushes on Lacey graphite can also be used as a pressure tube type graphite-moderated boiling water reactor neutron moderator. The main purpose is refractory raw materials, especially carbon brick. Nature, natural graphite flake graphite formation can be divided and earthy graphite. Crystal structure due to the presence of a large number of delocalized electrons, graphite can be conductive, their crystal layer in a direction parallel with the resistivity of (2.5 ~ 5.0) × 10-6Ω · m, and a direction perpendicular to the layers resistivity of 3 × 10-3Ω · m. In the production and manufacturing process should pay attention to the following questions: First, the choice of high purity, low impurity content of petroleum coke and coal tar pitch as a raw material. Raw material boron impurity content is lower, due to the boron content equivalent to an increase of 1 × 10 section Lacey lmb graphite prices, high temperature graphitization most volatile metal impurities in 2800 ~ 3000 ℃, while boron is higher than 3000 ℃ hardly removed due to boron and carbon formation B4C3. The boron content in the raw material is extremely strict requirements, in addition to the production of raw materials external procedure has been more than 10 foreign reduce impurities and reasonable process system is also very important.
