FAKATOKANGA: Ko ngā tohu hangarau o runga ake nei he tohu noa iho mō ngā uara noa iho.
Tākai hua: 1 kg/pēke, tākai putea pepa konumohe, 10 kg/kātene (e ai ki te tono a ngā kiritaki kia tohua te tapanga)
Nitride boron He tioata tēnei i titoa mai i ngā ngota hauota me ngā ngota boron. Kua wehea te hanganga tioata ki: te nitride boron hexagonal (HBN), te nitride boron hexagonal (WBN) me te nitride boron cubic. I roto i ēnei, ko te tioata o te nitride boron hexagonal. He hanganga paparanga tōna rite ki te karāhe, e whakaatu ana i te paura ma ngāwari, whakahinuhinu, mimiti makuku, ā, he māmā hoki, nō reira e kiia ana hoki ko te "karāhe ma". Ko te kiato ariā ko 2.27g/cm3, ko te taumaha motuhake ko 2.43, ā, ko te pakeketanga Mohs ko 2.
Nitride boron hexagonal He pai te ārai hiko, he kawe wera. He pumau matū, kāore he ira rewa e kitea ana, 3000°C i roto i te hauota 0.1MPA, i roto i te hau whakaiti kūpapa, he ātete wera ki te 2000°C, ina whakamahia i roto i te hauota me te argon ka taea te eke te pāmahana ki te 2800°C, he ngoikore te pumau i roto i te hauota hāora, ā, kei raro iho i te 1000°C te pāmahana whakamahinga. Ko te tauwehenga whānui o te boron nitride hexagon he rite ki te kuata, engari ko te kawe wera he tekau ngā wā i te kuata. He pai hoki te hinu whakahinuhinu i ngā pāmahana teitei. He hinu whakahinuhinu totoka pāmahana teitei pai rawa atu me te kaha mimiti i te niutron, he pumau ngā āhuatanga matū, ā, he ngoikore te matū ki te nuinga o ngā konganuku rewa.
Nitride boron hexagonal Kāore e rewa i te wai matao. Ina kohuatia te wai, ka tino pōturi te waikura, ā, ka puta he iti noa te waikawa boric me te haukini. Kāore e tauhohe ki ngā waikawa ngoikore me ngā turanga kaha i te pāmahana rūma. He paku rewa ki te waikawa wera. Whakamahia te hauwai konutai me te hauwai pāhare pākawa rewa. Ka taea te pirau i te tukatuka. He nui te ātete ki te waikura ki ngā waikawa inorganic, alkalis, otinga tote me ngā whakarewa waro.
Ko ngā momo tono pēnei i:
| Kaihoko tuku pokepokea ai mō te hanga konganuku me te hinu whakahinuhinu mō te kukume waea | Motuhake i raro i te hikohiko pāmahana teitei, ngā rauemi ātete | Ka taea te whakamahi mō ngā wāhanga pāmahana teitei, pēhanga teitei, whakamarumaru me te whakamarara wera | Ngā tāpiringa ārai-kākahu mō te tango hinu totoka pāmahana teitei |
|
He whakamaroke hiri-wera mō ētahi atu tāpiringa polymer transistor |
Te whakamarumaru wera ā-rangi Rauemi |
I muri i te maimoatanga pāmahana teitei me te pēhanga teitei, ka taea te huri hei nitride boron cubic he rite te pakeke ki te taimana. |
Ngā rauemi hangahanga o te tauhohenga ngota |
|
He pai mō te pūwero miihini rōkete rererangi |
Te hiko ngaohiko teitei me te auau teitei me ētahi atu. te ārai pewa katote |
Te whakarewa e whakamahia ana mō te mowhiti wehewehe maitai whakarewa tonu |
Ngā momo whakakikorua konumohe kiriata pūnga katoa |
|
Ngā momo putea konumohe hou katoa me ētahi atu… |
He maha ngā rauemi whakakikorua konumohe ārai-tinihanga laser |
Whakamahia i roto i ngā whakakī whakapaipai |
Ngā tāpiringa whakarei wera rauemi ārai pāmahana teitei |
★Tohutohu haumaru: He hua ā-ahumahi tēnei, kāore e taea te kai, me mau ngā kopare haumaru me ngā karapu rapa i te wā e whakamahia ana.
Ngā take rokiroki me te kawe:
1. Kāore tēnei hua e mura, e pahū hoki, ā, ka taea te penapena me te kawe hei matū whānui.
2. Penapena ki te wāhi hauhautanga, maroke, ārai i te ua, te makuku, me te karo i te kai hē.
