    摘要: The refractory mortar cured material of the invention formed in the surface or joint portions of a ceramic refractory material such as fire bricks used in the lining of melting furnace or firing furnace used at high temperature is composed by kneading ceramic particles with an inorganic binder having silanol group together with water, and forming the kneaded mortar on the surface of a ceramic base material. The average particle size of ceramic particles in the refractory mortar is 10 to 50 μm, the difference of 90% particle size and 10% particle size is 10 μm or more to 60 μm or less, the average pore size of the refractory mortar cured material is 5 to 25 μm, and the width of pore size distribution is 20 to 80 μm, so that the cracks may be suppressed. More preferably, the bulk density is 0.9 to 1.5 g/cm3.

    摘要: A carbon foam material with an improved oxidation resistance is created by blending formaldehyde with phenol to form a reactive mixture, polymerizing the reactive mixture with a non-oxidation promoting basic catalyst to form a resin article, foaming the resin article to create phenolic foam, and carbonizing the phenolic foam to create the carbon foam with an increased oxidation resistance. Specifically, the oxidation resistant carbon foam has a sodium content of approximately 0%. This inventive foam may also contain one or more oxidization inhibitors to impede the oxidation of the carbon foam when the foam is exposed to an oxidizing environment.
