| 1. | As a super refractory , nature flaky graphite has many advantages such as high thermal conductivity , high thermal shock resistance , excellent high - temperature strength , excellent machinability , high sublimation temperature and low thermal expansion coefficient . unfortunately , the poor water wettability , low density and flaky structure of graphite surface limit its application with large quantity
天然鳞片石墨以其热膨胀小，导热性、抗热震性和化学稳定性好等诸多优点而成为适应钢铁冶炼苛刻环境耐火材料的原料，但石墨在水中的润湿性、分散性差以及在空气中易氧化等缺点限制了它的进一步应用。 |
