Flake Graphite

Posted by Anna Zhao on July 23rd, 2019

Introduction of the flake graphite

Flake-graphite is probably the most familiar of the natural flake graphite materials. Most people are familiar with the finely powdered graphite used as a lock lubricant, or the “lead” in pencils. Both of these products typically contain natural flake graphite powder. As the name implies flake graphite has a distinctly flaky or platy morphology. All graphite has a flaky morphology on some level, but in most instances flake-graphite has this structure regardless of particle size.

Types of graphite

Graphite generally occurs in one of three forms:

Microcrystalline or amorphous;

Crystalline lump or vein;

Crystalline flake

Applications of flake graphite

Refractory materials,lubricant materials ,graphite crucible materials,carbon brush,lithium-ion battery materials,pencil lead materials, cast coating materials.. Crystalline flake graphite is widely used as an essential nonmetallic mineral in almost all industries. It can be used as high quality refractory material or coatings in metallurgical industry, black pencil
