Thermal and electrical conductivity of the
graphite refractory is very high, four times higher conductivity than stainless steel,
two
times higher than carbon steel, 100 times higher than non-metallic. Its thermal
resistance, not more than steel, iron, lead, metal materials, and reduce the
thermal conductivity increases with temperature, and this type of metal
materials in general, at high temperatures, the graphite tends to even the
adiabatic state. Therefore, under conditions of ultra-high temperature
insulation properties of the graphite is very reliable.
Graphite has good lubricity and plasticity,
graphite friction coefficient is less than 0.1, can be expanded into a
breathable translucent graphite flakes in a large high-strength graphite
hardness, as well as diamond tools are difficult to process.
Advanced refractory and coatings are widely
used in metallurgical industry, steel core light industry, electrical industry,
carbon brush, electrode in battery industry, fertilizer industry catalyst.
Graphite after processing, can produce graphite, graphite paper, graphite
sealing materials and other graphite products, has become an important
non-metallic mineral raw materials in various industrial sectors.
