High Purity 99.9% Expandable Graphite Powder Flake Graphite Powder Price CAS 7782-42-5 Flake Graphite
Brief Introduction of Flake Graphite
Product name: High Purity 99.9% Natural Flake Graphite Powder
Description of Flake Graphite
The graphite crystals of natural flake graphite are scaly. They are transformed under high-intensity pressure and are divided into large-scale and fine-scale. It is one of the best flotation ore in nature, and high-grade graphite concentrate can be obtained through multiple grinding and selection. The floatability, lubricity and plasticity of this type of graphite are better than other types of graphite. Therefore, it has the greatest industrial value. The required pressure is usually greater than 1 gigapascal (75,000 psi), and the required temperature is usually greater than 750 degrees Celsius (1,380 F).
Since carbon deposits form natural flake graphite when they are under pressure and temperature, natural flake graphite powder is most commonly found in metamorphic rocks, and the deposits are fairly evenly distributed throughout the rock. Graphite has large flakes, large flakes, medium flakes and fine flakes.
Depending on the application, the purity and/or size of natural flake graphite powder may be more important. The spherical industry requires large-size and flake graphite, while the refractory industry mainly focuses on the flake size.
