1．ʻO ka waika Boric he pūhui crystalline i hana ʻia e ka hoʻoheheʻe ʻana i ka boron trioxide i loko o ka wai.He ʻakika inorganic ia, me ka nui o ka waikawa tetraboric H2B4O7 (ʻike pū ʻia ʻo pyroboric acid), metaboric acid (HBO2) n a me orthoboric acid H3BO3 (i ʻike ʻia ʻo orthoboric acid).I waena o lākou, ʻo ka waika orthoboric ka ʻike wai paʻa loa.ʻO ka waika Orthoboric, i kapa ʻia hoʻi he waika boric no ka pōkole, he aniani pauka keʻokeʻo a i ʻole triaxial chemicalbook scaly junction crystal me ka luster.He ʻawaʻawa iki kona ʻono.Manaʻo ʻia ka momona i ka pili ʻana me ka ʻili.ʻAʻole ʻono a hiki ke hoʻoheheʻe ʻia i ka wai, ethanol, glycerin, ethers a me ka essence.ʻAkaʻawaʻawaʻawaʻa ka waiʻona.Hoʻomaʻemaʻe ʻia ka waika Orthoboric i ka waikawa metaboric ke hoʻomehana ʻia i 70-100 ℃, ka waika pyroboric i ka wā i wela ai i 150 ℃ -160 ℃, a me ka anhydride boric (B2O3) i ka wā i wela ai i 300 ℃.
2．He ʻawaʻawa nāwaliwali ka hoʻonā wai, he waika Lewis maʻamau.Ma ke alo o ka waika hydrochloric, ka waikawa citric a i ʻole ka waikawa tartaric, hiki iā ia ke hoʻoikaika i ka solubility i ka wai.No laila, hiki ke hoʻomaʻemaʻe ʻia e ka recrystallization.
3. ʻO ka maʻamau, ʻaʻole ʻawaʻawa ka waika boric.ʻO ka maʻi make o nā mākua ma kahi o 15 ~ 20 grams no ka kilo o ke kaumaha o ke kino, aʻo nā keiki he 3 ~ 6 grams no ka kilokani o ke kaumaha o ke kino.ʻO ka nui o ka absorption hiki ke alakaʻi i ka make nui.ʻO nā hōʻailona mua ka luaʻi, ka maʻi paʻi, ka ʻili o ka ʻili, a hoʻohauʻoli ʻia ke kikowaena o ke kikowaena a laila hoʻopaʻa ʻia.ʻO ka hāʻule ʻole a i ʻole ka haʻalulu nui, maʻamau i ka 3 a 5 mau lā o ka make.ʻO ka ʻai pinepine ʻana i nā mea liʻiliʻi e hōʻiliʻili i loko o ke kino, e alakaʻi ana i ka make mau, anorexia, luhi, pupule, dermatitis, ʻōhule, a me nā maʻi menstrual.

Hoʻohana nui ʻia ka 1.Boric acid i nā huahana aniani, ʻoi aku hoʻi i ka wela a me nā huahana aniani kūpaʻa.Hiki ke hoʻohana ʻia ka boron carbide i hana ʻia me ka waika boric ma ke ʻano he abrasive.Eia kekahi, hiki ke hoʻohana ʻia i ka enamel, ka lāʻau lapaʻau ceramic glaze, nā puaʻa inorganic, fertilizers a me ka hana metallurgical.
2. Hoʻohana nui ʻia ia i ka ʻoihana aniani (ke aniani optical, ke aniani kūpaʻa waikawa, ke aniani pale wela, ka fiber aniani no nā mea insulating), hiki ke hoʻomaikaʻi i ka pale wela a me ka ʻike o nā huahana aniani, hoʻomaikaʻi i ka ikaika mechanical, a pōkole manawa hehee.I ka enamel a me ka ʻoihana ceramic, hoʻohana ʻia ia e hoʻonui i ka nani a me ka wikiwiki o nā huahana enamel, a ʻo ia kekahi o nā mea hana o ka lāʻau glaze a me nā puaʻa.E like me nā mea hoʻohui a me ka cosolvent i ka ʻoihana metallurgical, ʻoi aku ka paʻakikī kiʻekiʻe o ke kila boron a me ka ductility rolling maikaʻi, hiki ke pani i ke kila nickel.ʻO ka waika Boric ka pale ʻana i ka corrosion a hiki ke hoʻohana ʻia ma ke ʻano he mālama mālama Buke, e like me ka pale ʻana i ka lāʻau.Hoʻohana ʻia ia i ka wili metala, ka ʻili, ke kiʻi a me nā ʻoihana ʻē aʻe, a me ka hana ʻana i nā dyes, nā lole pale wela a me nā ahi ahi, nā pōhaku kūlohelohe, nā capacitors a me nā mea hoʻonaninani.
3. Hiki ke hoʻohana ʻia e like me ka insecticide a me ka catalyst.ʻO ka Boron i loko o ka trace element fertilizers i ka mahiʻai he mea kūpono ia no nā mea kanu he nui a hiki ke hoʻomaikaʻi i ka maikaʻi o ka hua a me ka hua.ʻO ka waikawa Boric kekahi o nā kumu kumu no ka hana ʻana i nā boride ʻē aʻe.Hoʻohana nui ʻia nā pūhui boron i hana ʻia e ka boric acid i ka pale aupuni a me nā keʻena ʻoihana ʻē aʻe a me nā keʻena noiʻi ʻepekema.
