Title
(EN) GRAPHITE-CONTAINING REFRACTORY AND METHOD OF PRODUCING GRAPHITE-CONTAINING REFRACTORY
Abstract
(EN)

A graphite-containing refractory has higher bending strength and fracture energy than known refractories. The graphite-containing refractory has a graphite content of 1% to 80% by mass. 1000 to 300000 carbon fibers with a fiber diameter of 1 to 45 μm/fiber are bundled. The carbon fiber bundle has a length of 100 mm or more and is placed within the graphite-containing refractory to form the same.
