electrical calcined anthracite

Description:

electrical calcined anthracite
2) Electrical Anthracite Coal
Ash: 6.5% (max.)
VM: 0.8% (max.)
M: 1% (max.)
S: 0.3% (max.)
Size: 1 - 20mm, 95% (min.)
Real density: 1.82% (g/cm3) (min.)
Resistively: 700 Ohm/mm2

Packing: 1,000kg/bag

ECA is obtained by calcining Anthracite Electrically under high temperature of 1800-2400C in vertical shaft furnaces, finally coming out as semi-graphitized product with typical resistivity under 650 ohm.
