-188 Natural Flake Graphite as Raw Material

Product name: Intermediate carbon graphite

Specification: Particle size 150 um, carbon content 88%

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.

Use: Widely applied to high quality fire resistance material and coating of metallurgy industry, hot working material stabilizer of military industry, lead of light industry, carbon brush of electrical industry, electrode of battery industry, and catalyzer and additive of fertilizer industry. After further process, scale graphite can be made into the following high-tech products such as graphite colloidal graphite, graphite compacting material and composite material, graphite products, and graphite anti-friction additive, which are becoming important nonmetal mineral materials in every industry.

Index can be adjusted according to client requirement.

Our factory 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.

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 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.

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.
