Hiki ke hoʻopilikino ʻia ka pahu wiliwili kiʻekiʻe kiʻekiʻe carbide

(1) 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 ʻana, ʻo ka nui o ka 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 abrasive ʻē aʻe 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 / ℃.

(2) Kiʻekiʻe thermal conductivity
ʻO ka conductivity thermal kiʻekiʻe o SIC kekahi ʻano koʻikoʻi o kāna mau waiwai kino. ʻOi aku ka kiʻekiʻe o ka conductivity thermal o ka silicon carbide ma mua o nā mea refractory ʻē aʻe a me nā abrasives, ma kahi o 4 mau manawa o ka corundum. Silicon carbide thermal hoʻonui coefficient he haʻahaʻa, kiʻekiʻe thermal conductivity, e hana ana i kona mau huahana i loko o ke kaʻina hana o ka wela a me ka cooling ma lalo o emi thermal stress, a me ke kilikaki carbide huahana thermal haʻalulu kū'ē ke kumu maikaʻi.

(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.
