3297 Natural High Carbon Flake Graphite

Product name: High carbon graphite

Specification: Particle size 500um, carbon content 97%

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.

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.

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.

1. Used in A-energy and national defense industry: As a neutron moderator, graphite is used in atomic reactor. Uranium-graphite reactor, the most popular one in the world at present. Graphite meets the requirements of atomic reactor due to its properties of high melting point, stability and corrosion resistance when used as a moderator. When used in atomic reactor, impurity in graphite must not be in excess of some dozens of PPM. Especially the content of boron should be less than 0.5PPM. In national defense industry, graphite is used for production of nozzles of solid fuel for rockets, nose cone of missiles, and parts, insulation and ray-proof components of spacecrafts.

2. Graphite has the function to prevent scale from buildup in boilers. Experiment result shows that scale does not form on boiler surfaces if a certain quantity of graphite is added into water, usually 4~5g per ton. In addition, graphite can prevent rusts on metal chimney, building roof, bridge and pipeline.

3. Graphite can be used as pencil core, pigment and polishing agent. After special treatment, graphite is used in some industries as impervious graphite, highly oriented graphite and graphite fabrics.
