Typical characteristics for REGULAR COKE in comparison with those of METALLURGICAL COKE and of PREMIUM COKE calcined at 1620 K are:

	Regular coke	Premium coke	Metallurgical coke
Real densitya) (g × cm−3)	2.07–2.09	2.12–2.14	1.95–2.02
CTEb) (293–773 K) (K−1)	2.0 × 10−6	1.1 × 10−6	>3.0 × 10−6
CTEb) (293–773 K) (K−1)	1.0 × 10−6	0.5 × 10−6	2.0 × 10−6
Ash (wt%)	0.4	0.05	8–12
Sulfur (wt%)	1.0–1.5	0.6	0.6–5.0

a) Measured with m‐xylene.

b) Coefficient of thermal expansion.

REGULAR COKE is mainly used for the production of SYNTHETIC CARBON and GRAPHITE MATERIALS.
