鳞片石墨为天然显晶质石墨，其形似鱼鳞状，属六方晶系，呈层状结构，具有良好的耐高温、导电、导热、润滑、可塑及耐酸碱等性能。
鳞片石墨是一种层状结构的天然固体润滑剂，资源丰富且价格便宜。
鳞片石墨广泛用于治金工业的高级耐火材料与涂料。如镁碳砖、坩埚等。军事工业火工材料安定剂、冶炼工业脱硫增速剂、轻工业的铅笔芯、电气工业的碳刷、电池工业的电极、化肥工业的催化剂等。鳞片石墨经过深入加工，又可以生产出石墨乳，用于润滑剂、脱模剂、拉丝剂、导电涂料等。还可以生产膨胀石墨，用于柔性石墨制品原料，如柔性石墨密封件及柔性石墨复材料制品等。
根据鳞片大小不同，鳞片石墨可分为大鳞片石墨和细鳞片石墨，大鳞片石墨是指+50目、+80目、+100目的鳞片状石墨，低于这些目数的的鳞片石墨叫做细鳞片石墨。
Flake graphite is a natural crystalline graphite, which is similar to fish scales, belongs to the hexagonal crystal system, has a layered structure, and has good high temperature resistance, electrical conductivity, thermal conductivity, lubrication, plasticity and acid and alkali resistance.
Flake graphite is a natural solid lubricant with a layered structure, which is abundant and inexpensive.
Flake graphite is widely used in advanced refractories and coatings for the metallurgical industry. Such as magnesia carbon bricks, crucibles, etc. Stabilizer for pyrotechnic materials in military industry, desulfurization booster in smelting industry, pencil lead in light industry, carbon brush in electrical industry, electrode in battery industry, catalyst in fertilizer industry, etc. After deep processing, flake graphite can be used to produce graphite emulsion, which is used in lubricants, release agents, wire drawing agents, conductive coatings, etc. It can also produce expanded graphite, which is used as a raw material for flexible graphite products, such as flexible graphite seals and flexible graphite composite material products.
According to the size of the scales, flake graphite can be divided into large flake graphite and fine flake graphite, large flake graphite refers to +50 mesh, +80 mesh, +100 mesh flake graphite, below these flake graphite is called fine flake graphite.
