    Abstract: A porous refractory body, primarily a porous plug for the refractory lining of a vessel containing molten metal through which plug gas can be blown into the metal. This body has a cold crushing strength of not less than 200 kg/cm2 and consists of a coarse-grained refractory material with a minimum quantity of a suitable binding agent, and has permeable pores of a cross section not less than 0.05 mm and a gas permeability of at least 100, and preferably more than 500 nanoperm. The hot bending strength or modulus of rupture of the body at 1,400* C is from 20 - 60 kg/cm2. The refractory material is mixed with the binding agent, and the mixture is compressed with a pressure of at least 300 kg/cm2 before firing to bring substantially all of the grains into contact with adjacent grains.

    Abstract: A self-supporting composite filter for ultra filtration that can be backwashed has a central porous body which supports a thin diaphragm of fine porosity applied to the outer surface of the body. The body is porous, being formed by coarse grains and a binder. The diaphragm is thin in comparison to the filter body and is formed from a mix of fine grains, fibers and binder whose percentage composition, by volume, is in the ratio 60 to 40:40 to 20:30 to 10. The fibers are thin, 0.3 to 30 microns, and long, with a length at least 10 times their width to provide a microelasticity in the diaphragm. The absolute thickness of the diaphragm is 0.2 to 2 millimeters which is 5 to 75 times smaller than that of the support body. The ratio of the specific permeabilities of the support body to that of the diaphragm, for fluids in the laminar flow range, is between 2:1 and 100:1.

    Abstract: Dual pore-structured carbon and graphite consist essentially of a macroporous agglomeration of strongly bonded microporous grains of carbon or graphite the radii of the macropores therein being from substantially 10 to 350 .mu.m and those of the micropores from substantially 0.2 to 1.0 .mu.m, with the macropores being joined by intercommunicating channels which form a fluid permeable structure. Such carbon or graphite has a density of from 0.70 to 1.50 grams/cc., a permeability to gases of from 20 to 500 cm.sup.2 /sec/atmos and a porosity of from 30 to 50%. Such materials are produced by including in a mixture of tar or pitch and finely divided solid carbonaceous material in suitable proportions, a particulate eliminable non-carbon-forming material having a particle size of 10 to 350 .mu.m, which material is substantially insoluble in said mixture, in a proportion sufficient to secure the desired porosity, shaping and then heating the mixture to effect carbonization and/or graphitization thereof and, after the product has cooled, giving any appropriate after-treatment to eliminate any heat treated residue from said particulate material and leave the desired porous structure.
