ʻO ka poloka silika carbide pale a me nā tile

Hōʻike ʻo Silicon carbide (SiC) i ka ʻaʻahu koʻikoʻi a me ka pale ʻana i ka corrosion ma muli o kāna mau waiwai kino a me nā mea kemika.

Ma ke ʻano o ka pale ʻana, hiki i ka paʻakikī Mohs o ka silicon carbide ke hiki i 9.5, ʻelua wale nō i ka daimana a me ka boron nitride. ʻO kona kūpaʻa ʻaʻahu ua like ia me 266 mau manawa o ke kila manganese a me 1741 mau manawa o ka hao chromium kiʻekiʻe.

Ma ke ʻano o ka pale ʻana i ka corrosion, ʻo ka silicon carbide he kūpaʻa kemika kiʻekiʻe loa a hōʻike i ke kūpaʻa maikaʻi loa i nā waikawa ikaika, alkalis, a me nā hopena paʻakai. Eia nō naʻe, ʻoi aku ka nui o ke kūpaʻa ʻana o ka silicon carbide i nā metala i hoʻoheheʻe ʻia e like me ka aluminika a me ka zinc, a hoʻohana mau ʻia i nā crucibles a me nā mold i ka ʻoihana metallurgical.

I kēia manawa, ua hoʻohana nui ʻia ka silicon carbide me ka superhard structure a me kona inertness kemika i nā ʻoihana e like me ka mining, steel, and chemical, e lilo i mea koho kūpono ma lalo o nā kūlana hana koʻikoʻi.

Paʻa pale ʻaʻahu Silicon carbideHe mea nui ka hoʻokaʻawale ʻana i nā huahana silicon carbide. ʻO nā waiwai kūʻokoʻa a me ka corrosion-resistant o ka silicon carbide e hoʻohana nui ʻia i nā mea wili e like me nā mine crushers a me nā wili pōleʻa, e hōʻemi ana i ka hoʻololi pinepine ʻana i nā mea hana i hana ʻia e ka lole a no laila e hoʻohaʻahaʻa i nā kumukūʻai mālama mīkini.

ʻO kēia ka hoʻohālikelike ʻana ma waena o nā poloka ʻaʻahu kūpaʻa silicon carbide a me nā poloka pale lole kuʻuna kahiko:
