Boron: Mai i ngā Rauemi Taketake ki te Matua Hangarau-Tirohia – Te Tātari i te Whakamahinga Tika o te Boron Parakore-Tirohia i roto i ngā Ārahi-Haumaru me ngā Marae Matatau
I ngā mara hangarau teitei e whai ana i ngā rohe iti rawa me te mahi tino pai, he mea nui ētahi huānga taketake.Pōroni,Ko te tohu huānga B, te nama ngota 5, tētahi o aua huānga. Ko tēnei matū whakarewa, e kitea ana i roto i ngā matū taiao anake, kua noho hei "huānga matua" e kore e taea te whakakore i roto i ngā mara pēnei i ngā haurua-ā-ira, ngā rauemi matatau, me te umanga karihi nā tōna hanganga hiko ahurei me ōna āhuatanga ā-tinana me te matū.
1. "Ngā Kaimahi Matua" o te Ahumahi Ārahi-ā-Irahiko: Te Whakaranu Tika me te Tipu Tioata
I roto i te umanga haurua-ira, ko te uara o te boron tioata parakore teitei kei roto i ōna kaha whakahaere tika kore e rite.
Ko te tūāpapa o te tāpiritanga momo-P: Ko te whakamahinga matua o Boron he tāpiritanga momo-P. Ko te Silicon (Si) te mea tino kaha o ngā rauemi semiconductor, engari he ngoikore te rere o te hiko. Ina whakauruhia tika ngā ngota boron ki roto i te whatunga silicon mā roto i ngā tikanga pēnei i te whakaurunga katote, te tohatoha pāmahana teitei rānei, e toru noa iho ngā irahiko kei roto i te anga o waho o te boron, ki te whakaritea ki ngā irahiko e whā o te silicon. Ka hangaia he "kōhao" ka taea te whakauru me te kawe i ngā irahiko, ka hangaia he semiconductor momo-P. He mea nui tēnei tukanga "tāpiritanga" ki te hanganga o te hononga PN—te poraka hanga matua o ngā taputapu semiconductor katoa, tae atu ki ngā diode, ngā transistors, me ngā thyristors.
Ko te kī ki ngā taputapu hiko me te tauine: I roto i ngā taputapu hiko me tu atu ki ngā ngaohiko teitei me ngā iahiko teitei (pēnei i ngā IGBT me ngā MOSFET hiko), ka whai hua ngā papa silicon kua tāpirihia ki te boron (i te nuinga o te wā i te rohe ātete teitei) ki te whakahaere i te tohatoha o te mara hiko me te whakarei ake i te ngaohiko tu atu o te taputapu. Hei tāpiri, i ngā pūnga tukanga matatau, me tino tika te hanga o ngā hononga tino pāpaku. Nā te iti o te radius ngota o te boron, ka taea te whakahaere pai ake i te tāpiri, ka tutuki ai ngā hiahia o ngā taputapu nanoscale.
Rauemi pūtake mō te tipu tioata kotahi: Haunga te tāpiringa, ka whakamahia hoki te boron tioata hei rauemi pūtake mō te whakatipu i te boron-whakapiringasiliconngā tioata takitahi mā te tukanga rewa. Ka puta i tēnei tikanga ngā poro silicon me te kawe hiko momo-P ōrite puta noa i te papa katoa, e whakarato ana i te turanga mō te hanga nui o ngā taputapu semiconductor tino ōrite.
2. Kei tua atu i ngā Semiconductors: Te Mahi Tino Pai a Boron i ngā Marae Maha
Ehara i te mea ko ngā haurua-ira anake ngā whakamahinga a Boron; he mea rongonui ōna pūhui me ōna isotopes i roto i ngā mara matatau maha.
Ngā Rauemi Hanganga Matatau: Nā te tino pakeke o te Boron (te pakeke o Mohs 9.5) he rauemi pai mō te whakapakari. Ko ngā muka boron me ngā uku boride he wāhanga matua i roto i te hanga rauemi hiato kaha-teitei, māmā, e whakamahia whānuitia ana i roto i te rererangi, ngā taputapu hākinakina mahi-teitei, me ētahi atu mara.
Karāhe Motuhake me ngā Uku: I roto i te hanga karāhe, mā te tāpiri o te boron oxide ka whakaitihia te tauwehenga o te whakawhānui wera, ka puta he ātete pai ki ngā ru wera. He pai ake tēnei karāhe borosilicate mō ngā taputapu taiwhanga (pēnei i ngā kapu ātete wera) me ngā taputapu tunu kai kounga teitei. Waihoki, mā te tāpiri o ngā matū boron ki ngā uku ka whakapai ake i tō rātou pumau wera me te kaha miihini.
Te hopukanga o ngā irahiko me te umanga karihi: Kei roto i te boron tūturu te 20% o te isotope boron-10, he tino teitei te wāhanga whakawhiti hopukanga mō ngā irahiko wera. Nā tēnei āhuatanga ka waiho te boron-10 (i te nuinga o te wā he boron carbide, he waikawa boric rānei) hei rauemi tokotoko whakahaere tino nui, hei rauemi tiaki irahiko, me te kaihoko haumaru mō ngā pūnaha whakaweto ohorere i roto i ngā tauhohenga karihi.
Te Hanganga Waro me te Rongoā: I roto i ngā mara matū me te rongoā pai, he mea nui ngā matū kei roto te boron (pēnei i ngā waikawa boronic me ngā esters boronic) hei takawaenga mō te hanga hononga waro-waro me te waro-heteroatom, inā koa i roto i ngā tauhohenga hononga Suzuki-Miyaura. Kei te piki haere te maha o ngā ngota waro kei roto te boron kei te whakawhanakehia hei rongoā hou. Hei tauira, kua noho ētahi aukati proteasome hei rongoā anti-matepukupuku nui.
3. Ko te kounga te tūāpapa o te hangarau: he tuku pono mai i Haina
I te aroaro o ēnei tono hangarau-tiketike whānui me te tono nui, kua eke ngā whakaritenga mō te parakore, te ōritetanga me te āhua motuhake (pēnei i te rahi matūriki me te āhua tioata) o ngā rauemi boron ki ngā taumata kāore i kitea i mua.
E mārama ana a UrbanMines Tech., he kaihanga me te kaiwhakarato matua o ngā rauemi boron parakore-teitei i Haina, ki te pānga nui o ngā āhuatanga o ngā rauemi ki ngā hua o muri mai. Mā te whakamahi i ā mātou raina whakaputa motuhake me te whakahaere, he tohunga mātou ki te whakarato i te boron tioata me te boron amorphous parakore-teitei kounga-haurua-haurua, me ngā momo matū boron kua whakaritea, ki ngā kiritaki o te ao.
E tino whakapono ana mātou ko ngā hua tino pai anake ka taea te whakatutuki i ngā hiahia o te hangarau hou. Nō reira, e whakapau kaha ana mātou ki te mahi tahi me ngā hoa R&D me ngā hoa hanga o te ao ki te pana tahi i ngā rohe o te hangarau, mai i ngā maramara ki te pūngao ma, mā te whakarato i ngā otinga rauemi boron mahi-teitei, pumau me te pono.
