浸渍石墨（也称为不透水石墨）是一种在过去60-70年中一直在工业上使用的材料。主要的工业用途是建造化学加工设备，其中石墨优异的耐腐蚀性和高导热性尤其有利。典型应用包括药品和磷肥的制造、钢铁酸洗、氯化有机物的加工、烟气处理、HCI和H2SO4的生产和回收，以及化学中间体的制造。用于建造石墨压力容器的不透水石墨是一种复合材料，由“原始”石墨组成，该石墨采用严格控制的压力/热循环浸渍树脂。

Impregnated graphite (also called impervious graphite) is a material that has been in industrial use for the past 60-70 years. The primary industrial use has been in the construction of chemical processing equipment where the exceptional corrosion resistance and high thermal conductivity of graphite is particularly advantageous. Typical applications include the manufacture of pharmaceuticals and phosphate fertilizer, steel pickling, processing of chlorinated organics, flue gas treatment, HCI and H2SO4 production and recovery, plus the manufacture of chemical intermediates. The impervious graphite used for the construction of graphite pressure vessels is a composite material, consisting of "raw" graphite that is impregnated with a resin using a tightly controlled pressure/heat cycle.
