We offer a complete product range of Graphite Powder

The use of graphite as a refractory material began before 1900 with the graphite crucible used to hold molten metal;

this is now a minor part of refractories. In the mid-1980s, the carbon-magnesite brick became important,

and a bit later the alumina-graphite shape. As of 2017 the order of importance is: alumina-graphite shapes,

carbon-magnesite brick, monolithics (gunning and ramming mixes), and then crucibles.

Features: -

Crucibles began using very large flake graphite, and carbon-magnesite brick requiring not quite so large flake graphite;
for these and others there is now much more flexibility in the size of flake required, and amorphous graphite is no
- longer restricted to low-end refractories. Alumina-graphite shapes are used as continuous casting ware,
such as nozzles and troughs, to convey the molten steel from ladle to mold, and carbon magnesite bricks line steel
converters and electric-arc furnaces to withstand extreme temperatures.
Graphite blocks are also used in parts of blast furnace linings where the high thermal conductivity of the graphite is critical.
High-purity monolithics are often used as a continuous furnace lining instead of carbon-magnesite bricks.
