Silicon carbide pauka: hoʻohana i ka wā e hiki mai ana? 

Kiʻekiʻe Maʻemaʻe Silicon Carbide Powder: He alakaʻi piha ʻO ka pauka silicon carbide (SiC) maʻemaʻe he mea koʻikoʻi i nā noi ʻenehana holomua. Hāʻawi kēia ʻatikala i kahi hiʻohiʻona piha o kāna mau waiwai, hoʻohana, hana hana, a me nā ʻano mākeke, e kālele ana i nā pono o ka poʻe loea e hana nei me kēia mea. ʻO ka hoʻomaopopo ʻana i kāna mau hiʻohiʻona ke kī i ka hoʻokō kūleʻa ma waena o nā ʻoihana like ʻole.

Ka hoʻomaopopo ʻana i ka pauka Silicon Carbide maʻemaʻe kiʻekiʻe

Kiʻekiʻe maʻemaʻe silika carbide pauda, i kapa pinepine ʻia ʻo SiC pauda, he ʻano crystalline o ka silicon carbide me nā mea haumia liʻiliʻi. He mea koʻikoʻi kēia maʻemaʻe kiʻekiʻe no kāna hana i nā noi koi. Hōʻike pinepine ʻia ka pae maʻemaʻe ma ke ʻano he pākēneka o ka ʻike SiC, me nā pākēneka kiʻekiʻe e hōʻike ana i ka liʻiliʻi o nā haumia. ʻO nā waiwai o ka pauka, e like me ka puʻunaue ʻana i ka nui o nā ʻāpana, morphology, a me ka ʻili o ka ʻili, ʻokoʻa ʻē aʻe ma muli o ke ʻano hana. Hoʻopili pololei kēia mau waiwai i kāna mau noi hope.

Hana Hana o High Purity Silicon Carbide Powder

Hoʻohana ʻia kekahi mau ʻano hana no ka hana ʻana kiʻekiʻe maʻemaʻe silika carbide pauda. ʻO nā mea maʻamau ka:

Kaʻina Acheson

ʻO ke kaʻina hana Acheson kahi hana maʻamau e pili ana i ka hopena wela kiʻekiʻe o ka silica (SiO₂) a me ke kalapona (C) i loko o ka umu uila. Hāʻawi kēia kaʻina i nā kristal SiC o nā ʻano nui a me nā ʻano like ʻole. ʻOiai he mea kūʻai liʻiliʻi, hana ia i ka pauka me ka maʻemaʻe haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me nā ʻano hana ʻē aʻe.

Hoʻopaʻa ʻia i ka mahu (CVD)

ʻO CVD kahi ala i hoʻohana nui ʻia no ka hana ʻana kiʻekiʻe maʻemaʻe silika carbide pauda me ka nui o ka ʻāpana a me ka morphology. Ke kinoea precursors, e like me silane (SiH₄) a me ka metana (CH₄), e hana i nā wela kiʻekiʻe e hana i nā ʻāpana SiC. Hāʻawi kēia ʻano hana i ka mana pololei i nā hiʻohiʻona o ka pauka, i kūpono no nā noi kūikawā. Ke alakaʻi nei hoʻi ʻo CVD i nā mea haumia liʻiliʻi ma mua o ke kaʻina hana Acheson.

Nā ʻano hana ʻē aʻe

Hoʻohana ʻia nā ʻano hana ʻē aʻe, e like me ka sol-gel synthesis a me ka hoʻemi ʻana o ka carbothermal, no ka synthesize SiC maʻemaʻe kiʻekiʻe. Hāʻawi kēia mau ʻano i nā pono kūʻokoʻa e pili ana i nā koi kikoʻī no ka nui o nā ʻāpana, ke ʻano, a me ka maʻemaʻe.

Nā noi o ke kiʻekiʻe maʻemaʻe Silicon Carbide Powder

ʻO nā waiwai kūʻokoʻa o kiʻekiʻe maʻemaʻe silika carbide pauda e hana i mea kūpono no ka nui o nā noi, me:

ʻOihana Semiconductor

Ma ka ʻoihana semiconductor, hoʻohana ʻia ʻo SiC e hana i nā substrates no nā mea uila uila kiʻekiʻe a me nā alapine kiʻekiʻe. ʻO ka conductivity thermal kiʻekiʻe a me ka bandgap ākea o SiC e hiki ai ke kūkulu i nā uila uila ʻoi aku ka maikaʻi a hilinaʻi.

ʻO nā mea ʻāpala

Ma muli o kona paʻakikī a me ke kūpaʻa wela kiʻekiʻe, kiʻekiʻe maʻemaʻe silika carbide pauda loaʻa ka hoʻohana nui ʻana ma ke ʻano he abrasive i ka ʻoki ʻana i nā mea hana, wili huila, a me nā pūhui polishing. ʻO kona mana ʻokiʻoki ʻoi aku ka maikaʻi e hoʻohālikelike ʻia me nā abrasives ʻē aʻe i koho ʻia i nā kaʻina hana ʻoihana like ʻole.

Nā mea hoʻopaʻa

Hāʻawi ka helu heheʻe kiʻekiʻe o SiC a me ka inertness kemika i kona hoʻohana ʻana i nā refractory, nā mea hiki ke kū i nā wela kiʻekiʻe loa. He mea koʻikoʻi kēia i nā noi e like me nā kapuahi metallurgical a me nā reactors wela kiʻekiʻe.

Keramika a me nā mea hoʻohui

Kiʻekiʻe maʻemaʻe silika carbide pauda He mea waiwai ia i nā seramika kiʻekiʻe a me nā composites, hāʻawi i ka ikaika kiʻekiʻe, ka paʻakikī a me ka pale ʻana i nā huahana hope loa. Hāʻawi kēia i nā noi like ʻole e like me ka pale kaua a me nā mea ʻenehana.

Ke koho ʻana i ka pauka Silicon Carbide maʻemaʻe kiʻekiʻe

ʻO ke koho o nā mea kūpono kiʻekiʻe maʻemaʻe silika carbide pauda e pili ana i nā pono noi kikoʻī. ʻO nā kumu nui e noʻonoʻo ai:

No ke kūlana kiʻekiʻe kiʻekiʻe maʻemaʻe silika carbide pauda a me nā huahana pili, e noʻonoʻo e ʻimi i nā koho mai nā mea hoʻolako kaulana e like me Inner Mongolia Xinxin Silicon Industry Co., Ltd. Hāʻawi lākou i kahi ʻano huahana i hoʻohālikelike ʻia e hoʻokō i nā koi ʻoihana like ʻole.

Ka hopena

Kiʻekiʻe maʻemaʻe silika carbide pauda he mea maʻalahi me nā noi he nui i nā ʻenehana holomua. ʻO ka hoʻomaopopo ʻana i kāna mau waiwai, nā ʻano hana, a me nā noi like ʻole ke kī i ka hoʻohana ʻana i kona hiki piha ma nā ʻoihana like ʻole. Pono ke koho ʻana i ka papa kūpono e noʻonoʻo pono i nā koi kikoʻī o kēlā me kēia noi. Ma ka noʻonoʻo pono ʻana i kēia mau mea, hiki i nā poʻe loea ke hōʻoia i ka hoʻohana pono ʻana i kēia mea kupaianaha.

'Ōlelo Aʻo: No ka ʻike maʻamau kēia ʻike a ʻaʻole pono e manaʻo ʻia he ʻōlelo aʻoaʻo ʻoihana. E kūkākūkā i nā palapala ʻenehana kūpono a me nā loea no nā noi kikoʻī.
