Mea hana kiʻekiʻe kiʻekiʻe B2O3 boron oxide pauka cas 1303-86-2
He aniani kala ʻole a he pauka paha ka boron oxide. He paʻakikī a palupalu ke ʻano, he laumania ka sufrace.
a ʻono ʻole. He kūpaʻa ia i ka wela a ʻaʻole e hoʻemi ʻia e ke kalapona i ka wā e incandescent ana, akā hiki i nā metala alkali, magnesium a me ka alumini ke hoʻemi iā ia i monomer boron. Ma kahi o 600 ℃, lilo ia i mea nui loa
wai mānoanoa. Hiki i ka boric acid anhydride ke omo ikaika i ka wai i ka lewa e hana i ka boric acid. He mea hoʻoheheʻe ia
i loko o ka waikawa, ethanol, wai wela, a hoʻoheheʻe iki ʻia i ka wai anuanu. Hiki ke hui pū ʻia ka boron oxide me kekahi mau oxide metala e hana i ke aniani me nā kala ʻano. He hui pū ʻia me nā metala alkali, keleawe,
ʻO ke kālā ʻokiʻoki, ke kēpau, ka arsenic, ka antimony, a me nā ʻokikene bismuth.
ʻO ka nui o ka boron oxide crystalline he 2.46g/cm3, ʻo ka nui o ka boron oxide amorphous he 1.80 ~ 1.84g/cm3, wahi hoʻoheheʻe 557 ℃, solubility g/100gH2O: 1.1(0℃), 15.7(100℃) Hoʻopili maʻalahi i ka wai, lilo
ʻūlū ma hope o ke omo ʻana i ka makū, a hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona.
Ke haʻahaʻa ka mahana, hiki i ka dehydration H3BO3 ke hana i nā kristal boron trioxide, Loaʻa i kēia kristal ka ʻāpana kūkulu tetrahedral BO4, ka nui o 1.805g/cm3, ka helu heheʻe 450 ℃, ʻO ka nui o ka boron oxide aniani
ʻo 1.795g/cm3, a palupalu mālie ia ke piʻi ka mahana, a lilo i wai ke hiki i ka mahana wela kiʻekiʻe, me kahi paila o 1500℃. Hoʻohui pololei ʻia ʻo Boron a me ka oxygen e mālama iā B2O3.
1. ʻO ka mea hoʻoheheʻe silicate
2. Nā mea hoʻohui mea semiconductor i loko
3. Nā aniani pale wela a me nā mea hoʻohui pale pena
4. Ka hoʻomākaukau ʻana o nā mea a me nā mea nui like ʻole o ka boride.
5. Ka hoʻomākaukau ʻana o nā mea a me nā mea nui like ʻole o ka boride.
6. Nā mea maka no ka enamel.
7. Hoʻohana ʻia e like me ke kemika i ka ʻoihana mīkini, mea maka no ka mālama wela ʻana i ka mea hoʻoheheʻe boron
8. Mea hoʻouluulu hana organik
9. Hoʻohana ʻia ka mahana kiʻekiʻe e like me nā mea hoʻohui lubrication.
10. ʻOihana ikehu ʻātoma, a me ka ʻoihana uila.

A i ʻole hiki ke hoʻopilikino ʻia e like me nā pono o ka mea kūʻai aku
Pono ka mālama ʻana ma kahi anu, maloʻo a me ka ea.
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
