    摘要: A unitary composite structure having improved flexural strength and a reduced coefficient of thermal expansion comprising a heterogeneous combination of a carbonaceous reinforcing material interbonded with a matrix material, wherein the said matrix material is a poorly graphitizing carbonaceous pitch containing polymerized and cross-linked aromatic components is disclosed. Graphite electrodes comprised of the poorly graphitized pitch matrix material acting as a binder and/or an impregnant are also disclosed. Processes for the preparation of the poorly graphitizing pitch, the composite structure, and particularly the graphite electrodes are disclosed as well.

    摘要: A process for forming pinhole free ultra-thin flexible sheet material from natural graphite comprising treating low ash natural graphite particles with an oxidizing agent to intercalate the graphite, introducing the particles after they are dried to less than 2% by weight water into a furnace preheated to at least 2000.degree. F. to cause rapid expansion to a specific volume of at least 800 cc/gm and compressing the expanded graphite to below 8 mils in thickness with a density of less than 1.3 g/cc.

    摘要: A pipe thread sealant paste composition comprising from about 30 to about 80 percent by weight of natural flake graphite particles of a size sufficient to pass through a 100 Tyler mesh sieve and a liquid carrier comprising a mixture of mineral oil and petrolatum. The paste composition preferably having a total ash content of no greater than about 1 percent by weight and containing leachable chlorides in amounts equal to or less than about 50 parts per million. The invention also relates to a method for preparing and applying the pipe thread sealant paste to pipe joints.
