ʻO ke kīʻaha silika carbide

I loko o nā ʻoihana e like me ka metallurgy, ka ʻenekinia kemika, a me ka ikehu hou, aia kahi pahu koʻikoʻi akā koʻikoʻi - ka crucible. Inā like nā kīʻaha kuʻuna me "nā kīʻaha laiki hao", a lailanā kīʻaha silika carbidehe mau mana hou o "nā uhi pale pale titanium". E like me ka "behind the scenes hero" o ka ʻoihana hou, ʻo kēia pahu aniani ʻeleʻele e wehewehe hou i nā kūlana palekana no nā hana wela kiʻekiʻe.
Decrypting 'Black Technology': The Natural Endowment of Silicon Carbide
ʻO Silicon carbide (SiC), ʻo ia ka mea nui o nā mea semiconductor o ke kolu o ka hanauna, e hōʻike pū ana hoʻi i ka mana kupaianaha i ke kahua o nā seramika. ʻO kēia kristal superhard i hana ʻia i hana ʻia he ʻano atomic e like me ka lattice daimana i kūkulu pono ʻia, e hāʻawi ana i ka mea me ʻekolu mau pono kūpono: ke kū ʻana i nā wela kiʻekiʻe ma luna o 1350 ℃ me ka hoʻololi ʻole ʻana i ka waihoʻoluʻu, maʻalahi i ke kūʻē ʻana i ka media corrosive, a me ka hoʻoili wela e like me nā conductors metala. ʻO kēia pale ʻekolu-dimensional o ka "heat resistance + corrosion resistance + thermal conductivity" waiho i nā metala maʻamau a i ʻole graphite crucibles ma hope loa.

Ka Mana Paʻa Kūlohelohe: Nā mea haki i nā ʻano hana ʻoihana
Ma lalo o nā kūlana hana koʻikoʻi, hōʻike nā silika carbide ceramic crucibles i ke kūpaʻa kupaianaha. I loko o ka hale hana metallurgical, hiki iā ia ke mālama i ka erosion wela me ka maʻalahi; I nā hopena kemika, mau ka neʻe ʻole ʻana ma nā wahi ʻino loa; I loko o ke keʻena hana ikehu hou, ua hōʻoia ʻia ka pololei o ka synthesis mea. ʻO ka mea ʻoi aku ka kakaikahi ʻo kēia 'diamana indestructible kino' hiki ke hoʻohana pinepine ʻia, me ka hōʻemi nui ʻana i ke alapine o nā mea hana.
Koho akamai: ʻIke ʻia ka waiwai no ka wā lōʻihi
ʻO ke koho ʻana i kahi silika carbide ceramic crucible ke koho ʻana i kahi naʻauao ʻoihana. ʻOiai ʻoi aku ka kiʻekiʻe o ka hoʻopukapuka mua e hoʻohālikelike ʻia i nā mea kuʻuna, hiki i kāna hana lōʻihi a paʻa ke pale pono i nā kumukūʻai huna e like me ka hoʻopau ʻana i ka hana a me ka pollution maka. Ke hōʻike nei ka hapa nui o nā pahu i nā hōʻailona o ka luhi i nā wela kiʻekiʻe, mālama mau nā kīʻaha silicon carbide ceramic i ko lākou pololei geometric mua, a ʻo kēia ʻano "lōʻihi" ʻo ia ka mea i makemake nui ʻia i ka ʻoihana hou.
Ua komo nui ʻo Shandong Zhongpeng i ka hana o ka silicon carbide ceramics no nā makahiki he nui, e hoʻomau mau ana i ka hoʻoikaika ʻana i nā waiwai waiwai ma o nā kaʻina hana hou, e hana ana i kēlā me kēia crucible he hoa hana hilinaʻi. Ma ke ala o ka ʻimi ʻana i ka maikaʻi loa a me ka palekana, ke kākau nei nā seramika silicon carbide i kahi kūlana hou no nā ipu ʻenehana hou me ko lākou "ikaika paʻakikī".
