pūmua boron monomer/paura boron kore-āhua CAS 7440-42-8
He maha ngā allotropes o te boron. Ko te boron amorphous ka kiia hoki ko te boron elemental me te boron monomer.
He paura parauri, he tioata hina kanapa rānei, ā, he ora tonu ōna āhuatanga matū. He pumau.
i raro i te hau me te pāmahana noa. Ka waikura ina wera ki te 300℃ ka tahuna i te 700℃, Ko te mura
he whero ina tahuna, ā, he kakariki te mura boron me te mimiti iti. Kāore e rewa i te wai, he waikawa hauwai
waikawa, etanoru, me te etere. Ka wairewa i roto i te otinga kawakore matao, ā, ka pakaru te hauwai,
ka waikuratia hei waikawa boric e te waikawa hauota kukū me te waikawa whanariki kukū. I te teitei
i ngā pāmahana, ka taea e te Boron te taunekeneke me te hāora, te hauota, te whanariki, ngā halogens me te waro, ka taea hoki e te Boron
ka hono tika ki ngā konganuku maha hei hanga i ngā borida. Ko te tauhohenga o te boron ki ngā matū waro i roto i
ko tēhea hāora kei waenganui i te boron me te waro.
Kei tētahi tūranga motuhake te boron kotahi i te rārangi wehewehe i waenga i ngā konganuku me ngā mea kore-konganuku i roto i te
ripanga ā-pūmotu. He huānga kore-whakarewa, he kaha te utu kino, he iti te pūtoro ngota, he kukū te
te utu karihi, me ngā āhuatanga kore-whakarewa e rite ana ki te silicon. Ko tōna kiato he 2.35g/cm3. Ko te pakeke he 9.3,
Ko te taumaha motuhake he 2.33 - 2.45, ko te ira rewa he 2300℃, ko te ira koropupū he 2550℃.

8. Kaiwhakaoho haumaru waka
9. Te whakarewa maitai koranu motuhake
10. Rauemi mata mō te hanga muka boron
11. I roto i te kaihoroi hau parahi rewa
12. Te whakarite i ngā rauemi katote kounga teitei, te rauemi mata o te lanthanum borida
13. Mō ngā ngota pūngao tauhohenga
14. Ka taea te whakamahi hei rōkete me te wahie pūngao-nui mō ngā pere
15. Ka taea te whakamahi i roto i te umanga ahi
16. Te hanga rauemi mata nui o te boron halide parakore-teitei
