-198 Natural High Carbon Flake Graphite as Base Material

As a nonmetal mineral substance,graphite is of the following physical and chemical properties:high temperature resistances,oxidation resistance,erosion resistance,heat resistance,shake resistance,high strength ,high flexibility,high self-lubrication,high conductivity of heat and electricity.As an indispensable nonmetal raw material in current high technolohy industry,the graphite products manufactured by Tianhe are mainly applied to the following industries:metallurgy,machinery,electronics,battery,chemical industry,light industry,military industry,national defence,astronavigation,and fire resistance industry.

Graphite is carbon crystal and nonmetal material with the natures of silver gray, soft texture, metal luster, Mohs hardness 1~2, specific gravity 2.2~2.3 and volumetric weight 1.5~1.8 in general.

Graphite features very high melting point. It starts to melt at 3000°C in vacuum and evaporates at 3600°C. Strength of most materials decreases under high temperature but, on the contrary, the strength of graphite will increase in double when it is heated to 2000°C. However, graphite's oxidation resistance property is poor and temperature rise may quicken the Oxidation process of graphite.

Graphite is noted for excellent thermal and electrical conductivity, which is 4 times that of stainless steel, 2 times that of carbon steel and 100 times that of most nonmetal materials. Of graphite, thermal conductivity is better than that of metals, including steel, iron and lead, but decreases when temperature rises. Unlike metals, when temperature is extremely high, graphite will be of thermal insulation. So, the property of graphite in heat insulation under high temperature is accountable.

Product name:  High carbon graphite 

Specification: Particle size 150um, carbon content 98%

Property: scale is thin,flexible and crystallized completely with excellent physical and chemical properties such as good temperature resistance,self-lubrication,conductibility,heat resistance,shake resistance,and erosion resistance.

Graphite features excellent lubrication and plasticity. Friction coefficient of graphite is less than 0.1. Graphite can be extended into poromeric and transparent thin flakes. Due to high strength, graphite is unlikely processed even with a diamond cutter.

Graphite has stable chemical properties and resists corrosions of acid, alkali and organic solvent. Currently, graphite has been widely used in modern industries.

1. Packing: 1 ton bag or as your requirements.

2. Shipping: By sea or train

The company owns a graphite mine with the largest reserve in China so its graphite products are noted for property stability and consistence. In addition, the company exploits high-grade natural graphite ores and conducts multi-stage grinding, multiple floatation selection, chemical and electro-chemical purification and ultra-micro pulverizing. Upon request, we produce graphite products with 80~99.9% carbon content and 0.5~500 micron size and satisfy customer’s special requirements in content of moisture, ash, above- and under-sieve and microelement as well as grain size distribution.
