Kaihanga paura waikura boron B2O3 kounga teitei cas 1303-86-2
He tioata karāhe, he paura rānei te waikura boron, kāore he tae. He mārō, he pakarukaru te kounga, he maeneene te kiriuhi.
ā, kāore he reka. He pumau te pāmahana, ā, e kore e whakaitihia e te waro ina mura ana, engari ka taea e ngā konganuku kawakore, te konupūmā me te konumohe te whakaiti i a ia ki te monomer boron. I te 600℃ pea, ka tino
wai matotoru. Ka taea e te waikawa boric anhydride te mimiti kaha i te wai i te rangi hei whakaputa waikawa boric. Ka taea te wairewa
i roto i te waikawa, te etanoru, te wai wera, ā, he paku wairewa ki te wai matao. Ka taea te whakakotahi i te waikura boron me ētahi waikura whakarewa hei hanga karāhe me ngā tae āhua. Ka tino whakaranua ki ngā konganuku kawakore, te parahi,
He hiriwa, he mata, he āheniki, he ānitomoni, me ngā waikura bismuth.
Ko te matotoru o te waikura boron tioata he 2.46g/cm3, ko te matotoru o te waikura boron amorphous he 1.80 ~ 1.84g/cm3, te ira rewa 557℃, te wairewa g/100gH2O: 1.1(0℃), 15.7(100℃) Ka mimiti ngāwari i te wai, ka noho
pōuriuri i muri i te mimiti i te makuku, ā, ka taea hoki te rewa i roto i te waipiro.
Ina iti te pāmahana, ka taea e te H3BO3 maroke te whakaputa i ngā tioata boron trioxide, kei roto i tēnei tioata te hanganga BO4 tetrahedral, te mātotoru 1.805g/cm3, te ira rewa 450℃, te mātotoru o te waikura boron karāhe.
ko te 1.795g/cm3, ā, ka ngawari haere ina piki te pāmahana, ka wai ina tae ki te pāmahana wera whero teitei, me te pāmahana koropupū o te 1500℃. Ka honoa tika te boron me te hāora hei pupuri i te B2O3.
