Coke

Oil Coke

(oil coke sales are temporarily suspended, new sales information in September)

Oil coke is obtained by coking the atmospheric residue from the distillation of shale oils in coke ovens. This product is a high-quality raw material for electrode production. Oil coke is characterised by low sulphur and metal (V, Zn, Ni and Na) content and good graphitisation.

Oil coke is used as a high-quality raw material for low electrical resistance and low specific consumption electrodes.

The technical specifications of oil coke

Property	Norm
Volatiles, %, max	9,0
Ash, %, max	0,6
Sulphur, %, max	0,5
Real density (after calcining at 1300 °C)^o, g/cm³, max	2,10
*Moisture mass fraction, %**	3,0

* – the value of moisture does not signify a decrease in product quality (rejectability) and is used for the purpose of transactions with consumers only.

Isotropic Coke

Isotropic coke is obtained by coking the atmospheric residue from distillation. Its uniform structure ensures stability and density. It is mainly used as a raw material for construction graphites.

The technical specifications of isotropic coke

Volatiles, %, max	9,0
Ash, %, max	0,4
Sulphur, %, max	0,5
Real density (after calcining at 1300 °C)^o, g/cm3	2,04-2,08
Moisture content, %	3,0
