ʻEleʻele ʻeleʻele maikaʻi no nā noi abrasive

Ke hoʻohana nei ʻo Silicon carbide (SiC) i ke one quartz a me ka petroleum coke a i ʻole ka lanahu, nā ʻāpana lāʻau e like me ka mea maka ma o ke kiʻekiʻe kiʻekiʻe o ka uila hoʻoheheʻe ʻana i ka umu hoʻoheheʻe ʻia. ka moissanite.In contemporary C, N, B ka oxide refractory maka mea i loko o kaʻenehana kiʻekiʻe, e like me ka silicon carbide e like me ka loa hoʻohana 'ia, kekahi o ka loa economic.Can e kapaia corundum one a refractory. o ka silika carbide hiki ke maheleia i elua eleele kilikaka carbide a me ka omaomao silika carbide, he eono-aoao aniani, kiko'ī umekaumaha o 3.20 ~ 3.25, ka microhardness o 2840 ~ 3320 kg / was.
