Name:graphite; Chemical
formula:C; Molecular
weight:*2.*1; CAS:********5; EINECS:********3; Melting
point:***2; Boiling
point:***7; Water solubility: insoluble in
water; Density:2.*5g/cm³; Appearance: black
solid; Hardness:1～2; Proportion:2.***2.*6g/cm3; Specific surface
area:***0m2/g; Classification: 1. Classified
according to the different crystal form: dense crystalline
graphite, flake graphite and cryptic
graphite; 2. Classified
according to the special molding method: isostatic pressure
graphite, molded graphite, extruded
graphite; 3. Classified
according to graphite particles:detail graphite, medium graphite
(particle size about 0.8mm ) and electrode graphite
(2~4mm). Characteristics: high temperature
resistance,good
conductivity and good thermal conductivity,The lubrication
performance depends on the graphite scale. The larger the scale,
the smaller the coefficient of friction and the better the
lubrication performance;Good chemical stability at normal
temperature, acid, alkali resistance and corrosion resistance of
organic solvent resistance;Strong plasticity, good thermal shock
resistance; soft graphite, black gray; greasy, pollute
paper; Application: 1. Metallurgy,
steelmaking:refractories, reductants; 2. Electrical
industry: manufacturing of electrode, brush, carbon, carbon
nanotubes, the positive pole of the mercury current, graphite
gasket, telephone parts, TV picture tube coating (conductive
material); 3. Machinery
industry: made of piston cup, seal ring and bearing, metal
processing (wear-resistant lubricating
material); 4. The
petroleum chemical industry, metallurgy, acid-base production,
synthetic fiber (production reactor, heat exchanger, condenser,
combustion tower, absorption tower, cooler, heater, filter and pump
equipment) 5. Atomic
energy industry and defense industry:neutron moderator, solid fuel
rocket nozzle, missile nose cone, parts of aerospace equipment,
thermal insulation materials and radiation protection
materials; 6. Boiler,
bridge, pipe:anticorrosive and antirust; 7. Glass
and papermaking:polishing agent and antirust
agent; 8. Pencils,
ink, black lacquer, ink and artificial diamond, diamond:raw
material; 9. Other
industries: automotive batteries, composite materials, casting,
sand-casting, molding and high-temperature metallurgical materials
etc.
