High Purity Natural Graphite Flakes Price 350 Expansion Rate
Expandable Graphite Powder For Fire Additives
High Purity Graphite
High purity graphite was made from reaction of flake graphite and
various kinds of acids. Acid removes the impurities inside flake
graphite, and boosts the purity to 99-99.98%. It is widely used in
advanced refractory materials and coatings in the metallurgical
industry, military industrial pyrotechnic material stabilizers,
pencil leads in light industry, carbon brushes in the electrical
industry, electrodes in the battery industry, Fertilizer industry
catalyst additives, etc.

High-purity graphite (also known as: scaly high thermal
conductivity carbon powder) has the advantages of high strength,
good thermal shock resistance, high temperature resistance,
oxidation resistance, small resistivity, corrosion resistance, and
easy precision machining. It is an ideal inorganic non-metal
Material. Used for processing and manufacturing electric heating
elements, structural casting molds, crucible boats for smelting
high-purity metals, heaters for single crystal furnaces, graphite
for EDM, sintering molds, electron tube anodes, metal coating,
graphite crucibles for semiconductor technology, Graphite anodes,
grids, etc. for emitting electron tubes, thyratrons, and mercury
arc rectifiers.
It has the advantages of high temperature resistance, corrosion
resistance, thermal shock resistance, self-lubricating, and small
resistivity, etc.
