metala kalapona silika

Silicon Carbide Metal: A Comprehensive GuideSilicon carbide (SiC) he mea kupaianaha me ka laulā o nā noi, i kapa pinepine ʻia ʻo ia. metala kalapona silika, ʻoiai ʻo ka ʻenehana he seramika. Hoʻopili kēia alakaʻi i nā waiwai, nā ʻano hana, a me nā hoʻohana like ʻole o kēia mea ikaika.

Hoʻomaopopo i ka Silicon Carbide

Na waiwai o Metala Kapili Silika

Metala kalapona silika, ʻike ʻia hoʻi ʻo carborundum, ʻoi aku ka paʻakikī, ʻelua wale nō i ka daimana. ʻO kēia paʻakikī paʻakikī, i hui pū ʻia me ka conductivity thermal kiʻekiʻe, ka inertness kemika, a me ka ikaika kiʻekiʻe, kūpono ia no nā noi koi. ʻO kona wahi hoʻoheheʻe kiʻekiʻe (ma kahi o 2730 ° C) e kōkua hou i kona kūpono no nā kaiapuni wela kiʻekiʻe. ʻO ke ʻano kristal kū hoʻokahi o SiC ka hopena i nā polymorphs like ʻole, e hōʻike ana kēlā me kēia mea i nā waiwai ʻokoʻa, e alakaʻi ana i nā noi i hoʻopili ʻia ma muli o ke ʻano kikoʻī o SiC i hoʻohana ʻia. ʻO kēia mau waiwai he mea kūpono loa ia no nā ʻano noi like ʻole ma nā ʻoihana lehulehu.

Hana Hana

ʻO ka hana ʻana o metala kalapona silika e pili ana i nā ʻano hana, ʻo ia hoʻi ke kaʻina hana ʻo Acheson, e hoʻohana ana i nā wela kiʻekiʻe e hana i ka silica (SiO2) a me ke kalapona (C) i loko o ka umu ahi arc. ʻO nā ʻano hana ʻē aʻe e pili ana i ka chemical vapor deposition (CVD) a me nā ʻenehana kiʻekiʻe e hiki ai ke hana i nā kristal SiC maʻemaʻe kiʻekiʻe i hoʻohana ʻia i nā noi holomua. ʻO ke ala kikoʻī i hoʻohana ʻia ma muli o ka maʻemaʻe i makemake ʻia a me ke ʻano aniani o ka huahana hope, e hoʻohuli ana i nā kumu e like me ke kumukūʻai a me ka noi.

Nā noi o Metala Kapili Silika

Noi Hana Hana

Hoʻohana nui ka ʻoihana ʻoihana metala kalapona silika i nā noi he nui. He mea koʻikoʻi kona paʻakikī i nā mea hana abrasive, wili huila, a me nā mea hana ʻoki. He mea koʻikoʻi ka inertness kemika i nā noi e like me nā crucibles wela wela a me nā linings no nā reactors kemika. Hoʻohui ʻia, ʻo kona hiki ke kū i nā kūlana koʻikoʻi loaʻa nā noi i nā kaʻina hana ʻenehana kahi i koʻikoʻi ai ka lōʻihi a me ke kū'ē.

Nā polokalamu uila

Ua loaʻa nā holomua hou metala kalapona silika he mea hoʻokani pila ma ka ʻoihana uila. Hiki i nā waiwai uila kūikawā o SiC ke hana i nā mana kiʻekiʻe, kiʻekiʻe-frequency e like me nā transistors a me nā diodes. He mea nui kēia mau mea i ka uila uila, e hāʻawi ana i nā pōmaikaʻi nui i ka maikaʻi a me ka hana i hoʻohālikelike ʻia i nā ʻāpana kumu silicon. He mea koʻikoʻi kēia ʻo SiC no nā noi e like me nā kaʻa uila, nā ʻōnaehana ikehu hou, a me nā mea hana ʻoihana kiʻekiʻe. Inner Mongolia Xinxin Silicon Industry Co., Ltd. (https://www.xinxinsilicon.com/) he kumu hoʻohālike nui o kahi hui i komo i ka hana a me ka hoʻolako ʻana i nā mea SiC kiʻekiʻe no ia mau noi.

Nā noi ʻē aʻe

Ma waho aʻe o ka hoʻohana ʻana i ka ʻenehana a me ka uila, metala kalapona silika loaʻa kona ala i nā ʻāpana ʻē aʻe. Hiki i kona biocompatibility ke kūpono no kekahi mau noi biomedical, ʻoiai ʻo kona kūpaʻa wela a me ka ikaika e hoʻohana ʻia i nā noi wela kiʻekiʻe e like me nā mea refractory a me nā pale pale.

Hoʻohālikelike ʻo SiC me nā mea ʻē aʻe

Hoʻohālikelike ka papa ma lalo nei metala kalapona silika me nā mea maʻamau ʻē aʻe:

Waiwai	Silicon Carbide	Aluminum Oxide	Tungsten Carbide
Ka paakiki (Mohs scale)	9.5	9	9-10
ʻO ka hoʻoili wela (W/mK)	120-390	30-40	50-60
Lae hehee (°C)	~2730	2050	~2870

Ka hopena

Metala kalapona silika he mea maʻalahi a me ka hana kiʻekiʻe me kahi ākea ākea o nā noi ma nā ʻoihana like ʻole. ʻO kona hui pū ʻana o nā waiwai he mea nui ia no nā holomua ʻenehana a me nā kaʻina hana ʻoihana. Ke hoʻomau nei ka noiʻi a me ka hoʻomaikaʻi ʻana o nā ʻano hana, ʻoi aku ka nui o ka hiki i ka wā e hiki mai ana no kēia mea kupaianaha. Nānā: Hoʻopili ʻia ka ʻikepili i ka papa ma luna a ʻokoʻa paha ma muli o ke kaʻina kikoʻī a me ke kaʻina hana. Hiki ke ʻike ʻia nā ʻike hou aʻe e pili ana i nā waiwai kikoʻī o nā mea SiC like ʻole ma o ka palapala ʻepekema a me nā ʻikepili waiwai mai nā mea hoʻolako e like me Inner Mongolia Xinxin Silicon Industry Co., Ltd.
