What is natural graphite? Natural graphite can be divided into two industrial types: crystalline (scale graphite) and cryptocrystalline graphite (soil graphite). In the crystalline graphite ore, the diameter of the graphite crystal is more than one μ m, scaly; the ore grade is low but good optional; graphite-associated minerals, often mica, long stone, quartz, treble, pyroxene, garnet, a small amount of pyrite, calcite, some with rutile, vanadium and other useful components; the ore is scaly, granite scale or granular crystal structure, sheet, hemp or block structure. According to the fixed carbon content, crystalline graphite can be divided into high-purity graphite, high-carbon graphite, medium-carbon graphite, and low-carbon graphite. Hidden ink is also known as earthen graphite or amorphous graphite. In crystalline graphite ore, the diameter of graphite crystal is less than one μ m, and the aggregate of microcrystals can be seen under an electron microscope; the ore has high grade but poor selectability; the minerals associated with graphite often have quartz and calcite; the ore has a fine scale-cryptocrystalline structure, massive or soil structure. Crystalline graphite ore is mainly distributed in contact with metamorphic deposits.
Main uses of natural graphite High-purity graphite (fixed carbon content more than or equal to 99.9%) is mainly used in flexible graphite sealing materials and nuclear graphite. Instead, a platinum crucible is used for chemical reagent melting. Lubricant base material, High carbon graphite (fixed carbon content 94.0%~99.9%) is mainly used in refractory materials, lubricant base material, brush raw materials, electric carbon products, battery raw materials, pencil raw materials, filling materials and coatings; Medium carbon graphite (fixed carbon content of 80%~94%) is mainly used in a crucible, refractory materials, casting materials, casting coatings, pencil raw materials, battery raw materials, and dyes; Low carbon graphite (fixed carbon content 50.0%~80.0%) is mainly used for casting coatings. Cryptocrystalline graphite is mainly used for pencils, batteries, electrodes, graphite emulsion, graphite-bearing ingredients, and battery carbon rod raw materials; no iron is required. Cryptocrystalline graphite is mainly used for casting materials, refractory materials, dyes, and electrode paste.
