SiC-keramik spiller en stadig vigtigere rolle inden for materialer. Derfor haster det med at udf\u00f8re yderligere forskning i SiC-materialer for at reducere produktionsomkostningerne, forenkle produktionsprocesserne og fremme udviklingen af SiC-keramiske produkter, samtidig med at deres fremragende egenskaber l\u00f8bende forbedres.<\/p>\n<p>sintret siliciumcarbid betragtes som den mest lovende sintringsmetode til SiC-sintring. siliciumcarbidkeramik med stor st\u00f8rrelse og kompleks form kan fremstilles ved atmosf\u00e6risk sintringsproces. GE Corporation i USA har vedtaget f\u00f8lgende foranstaltninger: \u03b2 - Tils\u00e6tning af bor og kulstof til SiC, sintring ved over 2000 \u2103 i inert atmosf\u00e6re og opn\u00e5else af sintret siliciumcarbid med densitet h\u00f8jere end 98% ved 2020 \u2103. Med Y2O3 og Al2O3 som sintringshj\u00e6lpemidler og YAG (Y3Al5O12) med lavt smeltepunkt som basiskomponent fyrede Shanghai Institute of Silicate, Chinese Academy of Sciences siliciumcarbidkeramik med en b\u00f8jningsstyrke og brudstyrke p\u00e5 henholdsvis 707 og 10,7 ved 1850 \u00b0C. Liu Baoying fra Shandong Silicate Research and Design Institute tilf\u00f8jede en passende m\u00e6ngde Al2O3 og Y2O3 som sintringsadditiver og lavede fine SiC-kompositkeramiske materialer med en relativ t\u00e6thed p\u00e5 97% ved 1780 \u2103 ved hj\u00e6lp af fugest\u00f8bningsprocessen, som kan im\u00f8dekomme behovene for industriel produktion af mekaniske t\u00e6tninger og slidst\u00e6rk keramik. Men indtil videre er forskningen om sintret siliciumcarbid ikke s\u00e6rlig grundig, hvilket skal uddybes yderligere.<\/p>\n<p><a href=\"http:\/\/siliconcarbide.net\/wp-content\/uploads\/2022\/12\/sintered-silicon-carbide.jpg\"><img decoding=\"async\" class=\"size-full wp-image-555 lazyload\" data-src=\"http:\/\/siliconcarbide.net\/wp-content\/uploads\/2022\/12\/sintered-silicon-carbide.jpg\" alt=\"sintret siliciumcarbid\" width=\"552\" height=\"461\" data-srcset=\"https:\/\/siliconcarbide.net\/wp-content\/uploads\/2022\/12\/sintered-silicon-carbide.jpg 552w, https:\/\/siliconcarbide.net\/wp-content\/uploads\/2022\/12\/sintered-silicon-carbide-300x251.jpg 300w\" data-sizes=\"(max-width: 552px) 100vw, 552px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 552px; --smush-placeholder-aspect-ratio: 552\/461;\" \/><\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>silicon carbide ceramic are more and more widely used because of their excellent high temperature strength, wear resistance, corrosion resistance and thermal shock resistance.
