CONSTITUTION:For example, a carbonaceous heat insulating material composed of a carbonaceous felt, expanded graphite compact, etc., is highly purified so as to provide <=10ppm content of inorganic impurities (except carbon and silicon components) therein by a conventional well-known method. The aforementioned high purification is normally carried out by a method for bringing a gas containing, e.g. a halogen into contact with a heat insulating material at a high temperature under reduced pressure, converting the inorganic impurities into readily volatile metal halides having a high vapor pressure and eliminating the inorganic impurities from the aforementioned material. A SiC layer is then formed on the surface of the resultant highly purified heat insulating material according to a well-known method to afford the objective highly oxidation- resistant carbonaceous heat insulating material.</description><edition>6</edition><language>eng</language><subject>ARTIFICIAL STONE ; CEMENTS ; CERAMICS ; CHEMISTRY ; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDINGMATERIALS ; CONCRETE ; LIME, MAGNESIA ; METALLURGY ; REFRACTORIES ; SLAG ; TREATMENT OF NATURAL STONE</subject><creationdate>1998</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19980813&DB=EPODOC&CC=JP&NR=2787164B2$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,776,881,25542,76289</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19980813&DB=EPODOC&CC=JP&NR=2787164B2$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>KONDO TERUHISA</creatorcontrib><creatorcontrib>KONDO NAOTAKA</creatorcontrib><title>JP2787164B</title><description>PURPOSE:To obtain the subject carbonaceous heat insulating material having high oxidation resistance and hardly any contamination with coal dust and inorganic impurities by highly purifying the amount of the inorganic impurities in a carbonaceous heat insulating material to a specific content or below and depositing silicon carbide on the surface thereof.
