Ke hoʻonui mau nei ka nui o ka mākeke a me ka hiki ke hana o ka hafnium tetrachloride papa uila ma Kina.
Ua hoʻokuʻu ʻia ke Kikowaena Noiʻi ʻOihana Manaʻo Hou o Kina ma Malaki 5, 2026
ʻO ka hafnium tetrachloride papa uila e pili ana i ka hafnium tetrachloride maʻemaʻe kiʻekiʻe me ka maʻemaʻe o 99.95% a ʻoi aku paha.
ʻO ka hafnium tetrachloride, me ke ʻano molekalaHfCl4a me ke kaumaha molekala o 320.302, he pauka kristal keʻokeʻo. He mea ʻino ia a hiki ke puhi i nā maka a me ka ʻili. He mea hoʻonāukiuki hoʻi ia i ka ʻōnaehana hanu. Loaʻa iā ia kahi kiko heheʻe o 320°C a hiki ke sublimate. He maʻalahi ia e hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka methanol a me ka acetone. Hoʻopili ia me ka wai e hoʻokuʻu i nā kinoea ʻawahia. He hygroscopic ia a palaho maʻalahi ke hōʻike ʻia i ka lewa a pono e mālama ʻia i loko o kahi pahu i hoʻopaʻa ʻia.
"2025 Kina Electronic Grade Hafnium Tetrachloride Market Special Survey and Enterprise '15th Five-Year Plan' Suggestion Report" i hoʻokuʻu ʻia e ke Kikowaena Noiʻi ʻOihana Manaʻo Hou, hoʻohana nui ʻia ka hafnium tetrachloride papa uila i ka ʻoihana semiconductor ma ke ʻano he mea mua semiconductor. Hoʻokomo ʻia a ulu ʻia e like me nā kiʻiʻoniʻoni lahilahi e pili ana i ka hafnium me ka hoʻohana ʻana i nā kaʻina hana e like me ka atomic layer deposition (ALD) a me ka chemical vapor deposition (CVD). Loaʻa i nā kiʻiʻoniʻoni lahilahi e pili ana i ka hafnium kahi dielectric constant kiʻekiʻe, e lilo ana lākou i hoʻokahi o nā mea nui no ka hana ʻana i ka papa dielectric puka o nā transistors liʻiliʻi, hana kiʻekiʻe o ka hanauna e hiki mai ana. Hiki i ka hafnium tetrachloride papa uila ke hoʻokō i ke ʻano hoʻomohala o nā kaʻina hana hana chip e hoʻemi mau ana, a ke hoʻonui mau nei kona wahi mākeke. Eia kekahi, ma muli o kona mau waiwai optical maikaʻi loa, nā waiwai mechanical, a me ke kūpaʻa thermal, hiki ke hoʻohana ʻia ka hafnium tetrachloride papa uila i ka hana ʻana i nā kiʻiʻoniʻoni lahilahi optical, nā LED mana kiʻekiʻe, nā mea optoelectronic kokoke i ka infrared, a me nā keramika wela kiʻekiʻe.
Hoʻopilikia pololei ka maikaʻi o ka ʻenehana hoʻomaʻemaʻe i ka maʻemaʻe a me ke ʻano o ka hafnium tetrachloride papa uila. I nā makahiki i hala iho nei, ua piʻi ka nui o nā palapala hoʻopaʻa e pili ana i ke kaʻina hana hoʻomaʻemaʻe a me nā lako hana o ka hafnium tetrachloride papa uila ma Kina, me "kahi mea hana no ka hoʻomākaukau ʻana i ka hafnium tetrachloride papa uila" a me "kahi ʻano hana no ka hoʻomaʻemaʻe ʻana i ka hafnium tetrachloride papa uila".
I Mei 2025, ua hoʻolaha ʻia kahi palapala ʻae no ka "ʻano hoʻomaʻemaʻe no ka hafnium tetrachloride papa uila". Ma lalo o ka pale o ke kinoea inert, ua kau ʻia ka hafnium tetrachloride maka i loko o kahi waʻa quartz, a ma o nā kaʻina hana e like me ka hoʻomaʻemaʻe ʻana, ka hoʻomehana ʻana, ka hoʻomaʻemaʻe sublimation, a me ka hōʻiliʻili hoʻomaʻalili ʻana, hiki ke loaʻa nā huahana hafnium tetrachloride papa uila me ka maʻemaʻe o 5N a me 6N.
Ma ka mākeke Kina,ʻenehana UrbanMines.ʻO ka mea nui, ʻo Limited ka noiʻi, hoʻomohala, a hoʻolako i nā huahana hafnium tetrachloride papa uila me nā purities o ≥99.9%, 99.95%, a me ≥99.99%.
ʻO nā loiloi ʻoihana ma Newthink, ke hoʻonui mau nei ka hiki ke hana i ka hafnium tetrachloride uila o Kina. I Mei 2025, ua hōʻike ka National Environmental Protection Administration o Kina e ʻāpono ʻia a hoʻolaha ʻia ka hōʻike hopena kaiapuni no ka "Semiconductor New Materials Pilot Plant Project", a ke hoʻonui ikaika nei kekahi mau ʻoihana alakaʻi i ka ʻoihana i ka mākeke hafnium tetrachloride uila.
