Graphite-containing refractory material and method for manufacturing graphite-containing refractory material

摘要

Provided are a graphite-containing refractory material having higher bending strength and breaking energy than a conventional refractory material, and a method for manufacturing the refractory material. A graphite-containing refractory material having a graphite content in the range of 1% by mass or more and 80% by mass or less, wherein the carbon fibers having a fiber diameter in the range of 1 μm/piece or more and 45 μm/piece or less are bundled within the range of 1000 or more and 300,000 or less. , a carbon fiber bundle having a length of 100 mm or more is disposed therein.
