Nā Hiʻohiʻona:
Aia ʻo Boron ma kahi kūikawā ma waena o ka metala a me ka mea ʻole metala ma ka papa manawa o nā mea. ʻOi aku ka ikaika o kona mau waiwai kemika ma muli o ka uila maikaʻi ʻole ikaika loa, ka radius atomika liʻiliʻi a me ka hoʻouka nuklea kikowaena. He paʻa ia i ka mahana maʻamau, oxidized i ka wā e hoʻomehana ai i 300 ℃, a puhi ʻia inā e hoʻomehana ʻia i 700 ℃. He ʻono ʻole a ʻala ʻole. Ua like kona waiwai metala ʻole me ka silicon. Hiki iā Boron ke launa pū me ka oxygen, nitrogen, sulfur, halogen a i ʻole carbon etc. Hiki ke hoʻohui pololei ʻia me nā ʻano metala he nui e hana i nā hui boronic. Eia kekahi, hiki ke hana pū ʻia ka boron me nā hui organik e hana i kekahi mau hui, kahi e pili pono ai ka boron i ke kalapona, a i ʻole ka oxygen ma waena o ka boron a me ke kalapona.
Nā noi:
Hoʻohana nui ʻia ʻo Boron i ka metallurgy, electronics, medicine, ceramics, nulear industries a me ka ʻoihana kemika etc., hoʻohana ʻia ia ma ke ʻano o ka hui ʻana a i ʻole i hoʻohui ʻia i loko o kekahi mau alloys ma ke ʻano he addend. Hiki ke hoʻohana ʻia i ka hoʻoheheʻe ʻana i kekahi mau kila alloy kūikawā a ma ke ʻano he mea wehe kinoea no ke kila hoʻoheheʻe, i loko o ke pou puhi-entraining o ka paipu puhi-entraining i loko o ka ʻoihana, i loko o ka lāʻau hoʻomalu o ka reactor atomic, a i loko o nā wahie ikehu kiʻekiʻe no ka rocket. He mea nui ia no ka hana ʻana i nā borons halogenated maʻemaʻe kiʻekiʻe, he mea hoʻi no ka hana ʻana i nā ʻano hui boronic like ʻole. Hiki ke pani ʻia a mālama ʻia ka nui o nā metala hanohano a kakaikahi e ia. Hiki ke hoʻohana ʻia ʻo Boron a me kāna mau hui ma ke ʻano he mea hoʻoulu no kekahi mau hopena kemika organik, a pēlā aku.
Pūʻolo：
Hoʻopaʻa ʻia ia i loko o nā ʻeke pepa alumini me ka mīkini hakahaka, kahi i waiho ʻia ai ka ʻeke plastik.
Kaumaha ʻupena 1kg i ka ʻeke, 5kg/pahu pepa, 10kg/pahu pepa, 25kg/pahu pepa
Ka mālama ʻana：
Pono e mālama ʻia i loko o kahi hale mālama malu, ea a maloʻo. Hoʻokahi makahiki kona ola papa.
Hiki ke hoʻohana ʻia ka huahana inā piʻi i ka maʻamau ma o ka hoʻāʻo hou ʻana ma hope o ka lā i kuhikuhi ʻia.
Nā memo palekana
Ua manaʻo ʻia he mea ʻawahia ka huahana ma ka hanu ʻana a me ka ʻai ʻana, ʻo ka hanu ʻana e loaʻa ka hopena ma ke kikowaena o ka ʻōnaehana nerve, ʻo ka ʻai ʻana e alakaʻi i ka hoʻoulu ʻana o ke kahawai o ka ʻōpū a me nā ʻōpū a me ka make ʻana o ka boron, ʻo ka hoʻopā ʻana me ka ʻili a i ʻole nā maka e alakaʻi i ka hoʻoulu iki ʻana, pono e komo i nā aniani palekana, ka pale maka gauze pale lepo, nā mīkina lima laholio i ka wā e lawelawe ai.
