1.Boric acid bụ kristal ogige kpụrụ site igbari boron trioxide na mmiri.Ọ bụ acid inorganic, tumadi gụnyere tetraboric acid H2B4O7 (nke a makwaara dị ka pyroboric acid), metaboric acid (HBO2) n na orthoboric acid H3BO3 (nke a makwaara dị ka orthoboric acid).N'ime ha, orthoboric acid nwere mmiri kachasị mma.Orthoboric acid, nke a na-akpọkwa boric acid maka nkenke, bụ kristal ọcha ntụ ntụ ma ọ bụ triaxial chemicalbook scaly junction crystal with luster.Ọ nwere ntakịrị ụtọ ilu.Ọ na-enwe mmetụta abụba na kọntaktị na akpụkpọ ahụ.Ọ bụ enweghị isi na soluble na mmiri, ethanol, glycerin, ethers na isi.Ihe ngwọta nke mmiri na-adịghị ike bụ acidic.Orthoboric acid na-eji nwayọọ nwayọọ na-agbaze na metaboric acid mgbe ọ na-ekpo ọkụ ruo 70-100 ℃, pyroboric acid mgbe ọ dị ọkụ ruo 150 ℃ -160 ℃, na boric anhydride (B2O3) mgbe ọ dị ọkụ ruo 300 ℃.
2. Ngwọta mmiri na-esighi ike acidic, nke bụ ụdị Lewis acid.Na ọnụnọ nke hydrochloric acid, citric acid ma ọ bụ tartaric acid, ọ nwere ike ịkwalite solubility na mmiri.Ya mere, enwere ike sachaa ya site na recrystalization.
3. N'ozuzu, boric acid anaghị egbu egbu.Ọgwụ na-egbu egbu nke ndị okenye bụ ihe dịka gram 15 ~ 20 kwa kilogram nke ịdị arọ ahụ, ebe nke ụmụaka bụ 3 ~ 6 grams kwa kilogram nke arọ ahụ.Ọnụ ọgụgụ dị ukwuu nke nnabata nwere ike ibute oke nsi.Ihe mgbaàmà mbụ bụ vomiting, afọ ọsịsa, ọkụ ọkụ, na usoro nhụjuanya nke etiti na-enwe obi ụtọ na mbụ wee gbochie ya.Ọrịa ọbara siri ike ma ọ bụ ujo, na-emekarị n'ime ụbọchị 3 ruo 5 nke ọnwụ.Iri obere ọgwụ ugboro ugboro ga-agbakọba n'ime ahụ, na-eduga n'inwe nsị na-adịghị ala ala, anorexia, ike ọgwụgwụ, ara, dermatitis, isi nkwọcha, na nsogbu ịhụ nsọ.

A na-ejikarị 1.Boric acid mee ihe na ngwaahịa iko, karịsịa na ngwaahịa iko na-eguzogide okpomọkụ na chemical.Enwere ike iji carbide boron nke boric acid mee ihe dị ka ihe mgbochi.Na mgbakwunye, enwere ike iji ya na enamel, seramiiki glaze medicine, inorganic pigments, fatịlaịza na mmepụta metallurgical.
2.It na ọtụtụ-eji na iko ụlọ ọrụ (optical iko, acid na-eguzogide iko, okpomọkụ na-eguzogide iko, iko eriri maka insulating ihe), nke nwere ike melite okpomọkụ eguzogide na nghọta nke iko ngwaahịa, melite n'ibu ike, na-ebelata oge agbaze.N'ime ụlọ ọrụ enamel na seramiiki, a na-eji ya kwalite gloss na ngwa ngwa nke ngwaahịa enamel, ọ bụkwa otu n'ime ihe eji eme ọgwụ glaze na pigmenti.Dị ka ihe mgbakwunye na cosolvent na metallurgical ụlọ ọrụ, boron ígwè akpan akpan nwere elu ekweghị ekwe na ezi mpịakọta ductility, nke nwere ike dochie nickel ígwè.Boric acid nwere nguzogide corrosion na enwere ike iji ya dị ka ihe nchekwa akwụkwọ kemịkalụ, dị ka mgbochi corrosion osisi.A na-eji ya eme ihe n'ịgbado ígwè, akpụkpọ anụ, foto na ụlọ ọrụ ndị ọzọ, yana ịmepụta ihe eji esiji ákwà, ihe ndị na-ekpo ọkụ na ọkụ ọkụ, nkume nkume artificial, capacitors na cosmetics.
3. A pụkwara iji ya mee ihe dị ka ọgwụ ahụhụ na ihe na-akpali akpali.Boron nwere fatịlaịza mkpụrụ osisi n'ọrụ ugbo na-arụ ọrụ maka ọtụtụ ihe ọkụkụ ma nwee ike melite ogo na mkpụrụ.Boric acid bụkwa otu n'ime ihe ndị bụ isi maka imepụta borides ndị ọzọ.A na-eji ogige boron nke boric acid eme ihe na nchekwa mba yana ngalaba ụlọ ọrụ mmepụta ihe na ụlọ ọrụ nyocha sayensị.
