Other details:

Natural flake graphite is a type of natural crystalline graphite with a hexagonal layered structure, exhibiting a fish-scale appearance. It is a non-metallic mineral known for its high temperature resistance, electrical conductivity, thermal conductivity, and excellent lubricating properties

Appearance: fish scale-like or flaky, with a black or steel gray color and metallic luster

                        According to the mesh size, from Flake to powder form. but appearance is dark black micro-powder, the structure is  flake crystalline.


Classification criteria
It is classified into four categories based on the fixed carbon content:
High purity graphite: ≥99.9%
High-carbon graphite: 94%-99%
Medium carbon graphite: 80%-93%
Low-carbon graphite: 50%-75%

Technical Data

Items	Typical	Test Standard and Effection
Fixed Carbon Content	≥94-96%	ISO 8005
Volatile Matter	0.5~1.5%	ASTM D3175
Ash	2.0~ 5.5%	ISO 1171
Sulfur	500ppm	ASTM D4239
Moisture	≤0.5%	ASTM D3302
Flake size	+100 ~80mesh	Better fluidity in refractory materials
Packing Density	0.8-1.0 g/cm³	Affect the bulk density of magnesia carbon brick
Thermal Conductivity	100-150 W/(m·K)	Key indicators of thermal shock resistance
pH value	6-8	Avoid reacting with alkaline materials

Applications

Widely used in:
1. Advanced refractory materials and coatings for the metallurgical industry, such as magnesia-carbon bricks and crucibles.
2. Stabilizers for pyrotechnic materials in military industry, and desulfurization accelerators in metallurgical industry
3. Pencil lead for light industry
4. Carbon brushes in the electrical industry
5. Electrodes in the battery industry
6. Catalysts for the fertilizer industry, etc.
After undergoing deep processing, flake graphite can be further refined into graphite emulsion, which is used in lubricants, mold release agents, drawing agents, conductive coatings, etc. It can also be processed into expanded graphite, serving as the raw material for flexible graphite products, such as flexible graphite seals and flexible graphite composite materials
