The main graphite grades that we are producing
· GT - crucible graphite for manufacturing of refractory products, melting crucibles;
Application of crucible graphite (GT) increases the products heat conductivity, promotes the enhancement of their high temperature and heating speed resistance. Being practically infusible and chemically inert substance with respect to the most materials, the graphite imparts to products high inertness, improves their quality, gives a smooth surface to crucibles impeding a smelt sticking to it.
Low thermal expansion coefficient of graphite and connecting with that temperature stresses high resistance is the governing factor while choosing graphite for application as the important and indispensable accessory material in the metal-working, cast iron and steel industry, i.e. all over where effective area should be protected from the smelt direct influence. Significant advantage of graphite at such application is its non-wettability by completely reduced metals and neutral slag, as well as its strength at high temperatures.
Graphite using while casting parts improves formation quality, decreases amount of waste, and prevents burnt-on creation, the removal of which requires heavy energies and costs. Greensand molds and cores are coated with a layer of dry powdered graphite.

· GL - casting graphite for drilling, oil and gas producing industry, metal-working industry, cast iron industry, and steel-casting industry);
Application of foundry graphite (GL) for these purposes gives the highly significant results. The mold paints, being the water suspensions of graphite with the certain additives, are used for the dry moulds and cores as the antiburning-on material. The mold paints create the thin protective layer on the mould surface and prevent from direct attachment of the agglutinant sand fusible minerals to smelt.

· GE - battery graphite for manufacturing of high quality galvanic cells;
· GAK - graphite for manufacturing of accumulator battery;
Accumulator graphite (GAK). Natural crystalline graphite is applied in manufacture of carbon electrodes for electric furnaces and electrolysers where the special steels, magnesium, aluminum, ferroalloys, other ferrous and non-ferrous metals are smelted. Accumulator graphite is widely used as the additive for making of accumulators paste to reduce the electric current intermediate resistance.

· GSM - special low-ash graphite for manufacturing of artificial diamonds;
· EUZ-E - graphite for manufacturing of carbon electrodes;
Electro-carbon graphite (EUZ-E, EUZ-M) in the form of pastes and powders is also used for contacts sealing in the butt gaps. The graphite is indispensable while manufacturing sliding contacts (electro-brushes) where its antifriction properties mainly are used along with electrical and mechanical ones. The graphite brushes possess high mechanical strength, take heavy heat and electrical load, practically insensitive to rapture, and possess extremely low friction coefficient.
