He aha ka hafnium tetrachloride?

Hafnium tetrachloride, i ʻike ʻia ʻohafnium(IV) chloride or HfCl4, he hui me ka helu CAS13499-05-3. Hōʻike ʻia ia e ka maʻemaʻe kiʻekiʻe, maʻamau 99.9% a 99.99%, a me ka haʻahaʻa haʻahaʻa zirconium, ≤0.1%. ʻO ke kala o nā ʻāpana hafnium tetrachloride he keʻokeʻo a keʻokeʻo paha, me ka mānoanoa o 3.89 g/cubic kenimika a me kahi helu heheʻe o 432°C. ʻO ka mea nui, haki ia i loko o ka wai, e hōʻike ana i ka hana ʻana me ka wai.

Hafnium tetrachloridehiki ke hoʻohana ʻia ma ke ʻano he precursor i ka hana ʻana i nā ceramics ultra-high temperature. ʻIke ʻia no ko lākou kūpaʻa wela maikaʻi loa, hoʻohana ʻia kēia mau ceramics i nā ʻano hana wela kiʻekiʻe, e like me nā ʻōnaehana pale wela i ka ʻoihana aerospace a me ka hana ʻana i nā mea hana ʻoki a me nā crucibles. ʻO ka hiki o ka pūhui ke kū i nā mahana wela he mea nui ia i ka hoʻomohala ʻana i nā mea no nā ʻenehana holomua a me nā hoʻohana ʻoihana.

Eia kekahi,hafnium tetrachloridehe kuleana koʻikoʻi ma ke kahua o nā LED mana kiʻekiʻe. Hoʻohana ʻia ia i ka hana ʻana i nā phosphors, kahi mea koʻikoʻi i ka hana o nā LED. ʻO nā Phosphors nā mea e hoʻokuʻu i ka mālamalama i ka wā e ʻike ʻia ai i ka radiation a hoʻohui ʻia i ka hana LED ma o ka hoʻololi ʻana i ke kukui polū i nā kala ʻē aʻe, a laila e hoʻomaikaʻi ai i ka maikaʻi holoʻokoʻa a me ka maikaʻi o ke kukui.

Maʻemaʻe kiʻekiʻehafnium tetrachloridehiki ke hoʻopilikino ʻia e hōʻemi i ka ʻike zirconium i ka 200ppm, e hōʻoiaʻiʻo ana he kūpono ia no ke koi ʻana i nā noi kahi e hoʻopilikia ai nā haumia i ka huahana hope. He mea koʻikoʻi kēia pae o ka maʻemaʻe no ka hoʻohui maikaʻi ʻana o nā mea holomua, kahi mea koʻikoʻi ka hoʻomalu pono ʻana o ka haku mele.

I ka hōʻuluʻulu manaʻo,hafnium tetrachloride, me kona maʻemaʻe maikaʻi loa a me nā waiwai kūikawā, ua lilo ia i mea mua nui no ka hana ʻana i nā ceramics ultra-high temperature a hoʻokani i kahi hana koʻikoʻi i ka holomua o ka ʻenehana LED kiʻekiʻe. ʻO kāna versatility a me ka reactivity e lilo ia i mea hoʻohui i ka hoʻomohala ʻana i nā mea no ka ʻokiʻoki ʻana i nā ʻoihana ʻenehana a me nā ʻenehana.
