Kiʻekiʻe maʻemaʻe silika carbide e wili ana i loko o ka barela haʻahaʻa liʻiliʻi

(1) Ka ikaika mechanical kiʻekiʻe, e like me ka maikaʻi
Hiki i ka ikaika mechanical kiʻekiʻe ke pale i ka deformation mea, he mea nui loa.ʻOi aku ka ikaika mechanical o ka Silicon carbide ma mua o ka corundum.No ka laʻana, ʻo ka ikaika compressive o ka silicon carbide he 224MPa, ʻoiai ʻo ka corundum he 75.7MPa wale nō.ʻO 15.5MPa ka ikaika kulou o ka carbide silicon, a ʻo ka corundum he 8.72MPa.

(2) Ke pale wela kiʻekiʻe, ka helu liʻiliʻi o ka hoʻonui wela
Hana ʻia ʻo Silicon carbide i nā wela kiʻekiʻe.I kekahi ʻano wela wela, pono ka mea e loaʻa i kahi ikaika kaʻina hana, a hoʻokō i ka pololei o ka hana ʻana, a hiki i ka silicon carbide ceramics ke hoʻokō i kēia mau helu ʻelua.ʻO ka mahana hoʻohana kiʻekiʻe loa o ka silicon carbide ma kahi o 800 ℃, a ʻo ka wela o ke kila he 250 ℃ wale nō.Ma ka helu ʻino ʻana, ʻo ka awelika hoʻonui wela wela o SIC he 4.4 × 10-6/C ma ka laulā o 25 ~ 1400 ℃.ʻOi aku ka liʻiliʻi o ka helu hoʻonui wela o SIC ma mua o nā mea abrasives a me nā mea wela kiʻekiʻe.No ka laʻana, hiki ke kiʻekiʻe ka coefficient o ka hoʻonui wela o ka corundum e like me (7 ~ 8) × 10-6 / ℃.

(3) Ke kū'ē i ka corrosion
Silicon carbide ma muli o kona helu heheʻe (decomposition wela), kemika inertia a me ka thermal shock resistance he kiʻekiʻe, hiki ke hoʻohana ʻia no nā ʻano huahana silicon carbide ceramic, e like me nā huahana ceramic wili ʻana i nā mea hana, ka pā kaupaku a me ka sagger, zinc smelting industrial vertical ka umu hoʻoheheʻe cylinder me ka pōhaku silika carbide, alumini electrolytic cell lining, crucible, mea umu liʻiliʻi.
