Mea hana kiʻekiʻe B2O3 boron oxide pauka cas 1303-86-2
ʻO ka boron oxide he aniani aniani kala ʻole a i ʻole ka pauka. He paʻakikī a he palupalu ka maikaʻi, maʻalahi ka sufrace
a me ka ono ole. He paʻa ka wela a ʻaʻole e hoʻemi ʻia e ke kalapona i ka wā e kukui ai, akā hiki i nā metala alkali, ka magnesium a me ka alumini ke hoʻemi i ka monomer boron. Ma kahi o 600 ℃, lilo ia i mea nui loa
wai viscous. Hiki i ka boric acid anhydride ke komo ikaika i ka wai i ka lewa e hana ai i ka waikawa boric. Hiki ke hoʻoheheʻe
i ka waikawa, ethanol, ka wai wela, a hiki ke hoʻoheheʻe iki ʻia i ka wai anuanu. Hiki ke hoʻohui ʻia ka Boron oxide me kekahi mau mea metala e hana i aniani me nā kala ʻano. Ua hui pū ʻia me nā metala alkali, keleawe,
ʻO Sliver, lead, arsenic, antimony, a me ka bismuth oxides.
ʻO ka mānoanoa o ka crystalline boron oxide he 2.46g/cm3, ʻo ka nui o ka amorphous boron oxide he 1.80 ~ 1.84g/cm3, ka helu hoʻoheheʻe 557 ℃, solubility g / 100gH2O: 1.1 (0 ℃), 15.7 (100 ℃) E maʻalahi i ka wai. , lilo
turbid ma hope o ka lawe ʻana i ka makū, a hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona.
Ke haʻahaʻa ka mahana, hiki i ka H3BO3 dehydration ke hana i nā kristal boron trioxide, Aia kēia aniani i ka BO4 tetrahedral structural unit, density 1.805g / cm3, helu hoʻoheheʻe 450 ℃, Ka nui o ka aniani boron oxide.
ʻo 1.795g/cm3, a palupalu mālie ke piʻi aʻe ka mahana, a lilo i wai ke hiki i ka wela ʻulaʻula kiʻekiʻe, me kahi paila o 1500 ℃. Hoʻohui pololei ʻia ka boron a me ka oxygen e loaʻa iā B2O3.
1. Silicate decomposition cosolvent
2. Semiconductor mea dopants ma
3. ʻO nā mea aniani pale wela a me nā mea hoʻohui paʻi refractory pena
4. Ka hoʻomākaukau ʻana i nā mea a me nā ʻano mea nui o ka boride.
5. Ka hoʻomākaukau ʻana i nā mea a me nā ʻano mea nui o ka boride.
6. Nā mea maka no ka enamel.
7. Hoʻohana ʻia e like me ke kemika i ka ʻoihana mīkini, Raw material for heat treatment of boron dissolving agent
8. Mea hoʻolalelale hoʻohuihui
9. Hoʻohana ʻia ka wela kiʻekiʻe e like me ka lubrication additives.
10. ʻoihana ikehu atomika, a me ka ʻoihana uila.

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