Tšebeliso ea Sehlahisoa
Khalase / fiberglass
E sebelisoa bakeng sa tlhahiso ea khalase ea optical, khalase e thibelang acid, khalase ea organoborate le likhalase tse ling tse tsoetseng pele le fiber ea khalase, e ka ntlafatsa ho hanyetsa mocheso le ho pepeseha ha khalase, ho ntlafatsa matla a mochine, ho khutsufatsa nako ea ho qhibiliha.B2O3 e bapala karolo e 'meli ea ho phalla le ho theha marang-rang ha ho etsoa khalase le fiber ea khalase.Mohlala, tlhahisong ea fiber ea khalase, mocheso o qhibilihang o ka theoleloa ho thusa ho taka terata.Ka kakaretso, B2O3 e ka fokotsa viscosity, ho laola katoloso ea mocheso, ho thibela ho phunyeletsa, ho ntlafatsa botsitso ba lik'hemik'hale, le ho ntlafatsa ho hanyetsa ho tsieleha ha mechine le mocheso oa mocheso.Ka tlhahiso ea khalase moo ho hlokahalang sodium e tlaase, boric acid hangata e kopantsoe le sodium borates (e kang borax pentahydrate kapa borax anhydrous) ho laola tekanyo ea sodium-boron ka khalase.Sena ke sa bohlokoa bakeng sa khalase ea borosilicate hobane boron oxide e bontša ho qhibiliha ho hotle tabeng ea sodium e tlaase le aluminium e phahameng.
Enamel/ceramic
Enamel, indasteri ea ceramic bakeng sa tlhahiso ea glaze, e ka fokotsa katoloso ea mocheso oa glaze, ea fokotsa mocheso o folisang oa glaze, e le ho thibela ho phatloha le ho putlama, ho ntlafatsa ho benya le ho potlaka ha lihlahisoa.Bakeng sa likhalase tsa ceramic le enamel, boron oxide ke 'mele o motle oa ho phalla le ho theha marang-rang.E ka theha khalase (ka mocheso o tlase), ea ntlafatsa ho ikamahanya le maemo ha glaze e se nang letho, ea fokotsa viscosity le tsitsipano ea holim'a metsi, ea ntlafatsa index ea refractive, ea ntlafatsa matla a mochini, ho tšoarella le ho hanyetsa, ke karolo ea bohlokoa ea glaze e se nang lead.Boron frit e phahameng e butswa kapele mme e etsa glaze e boreleli ka potlako, e loketseng ho etsa mebala.Ka frit ea lithaele tse benyang ka potlako, B2O3 e hlahisoa e le boric acid ho netefatsa tlhokahalo e tlase ea sodium content.
Indasteri ea tlhokomelo ea bophelo
E sebelisoa ha ho etsoa setlolo sa boric acid, sebolaea likokoana-hloko, astringent, preservative joalo-joalo.
E thibelang lelakabe
Ho eketsa borate ho thepa ea celluloid ho ka fetola karabelo ea eona ea oxidation le ho khothaletsa sebopeho sa "carbonization".Ka hona e thibela lelakabe.Asiti ea boric, e le 'ngoe kapa e kopane le borax, e na le phello e khethehileng ho fokotsa ho chesa ha celluloid insulation, lehong, le lithaere tsa k'hothone ka materaseng.
Metallurgy
E sebelisoa e le tlatsetso le cosolvent tlhahiso ea tšepe ea boron ho etsa hore tšepe ea boron e be le boima bo phahameng le ductility e ntle ea rolling.Boric acid e ka thibela oxidation ea bokaholimo ba tšepe, brazing le casing welding.Hape ke thepa e tala ea ferroboron alloy.
Indasteri ea lik'hemik'hale
E sebelisoa ha ho etsoa liborate tse fapa-fapaneng, tse kang sodium borohydride, ammonium hydrogen borate, cadmium borotungstate, borohydride ea potasiamo joalo-joalo.Tlhahisong ea li-intermediate tsa nylon, asiti ea boric e bapala karolo ea matla ho oxidation ea hydrocarbons mme e hlahisa li-ester ho eketsa chai ea ethanol, ka hona e thibela ho tsoela pele ha oxidation ea lihlopha tsa hydroxyl ho hlahisa ketone kapa hydroxic acid.Indasteri ea manyolo bakeng sa tlhahiso ea likhoele tsa likerese, boron e nang le manyolo.E sebelisoa e le sesebelisoa sa ho hlahloba lik'hemik'hale bakeng sa ho lokisa buffer le mecha ea litaba e fapaneng bakeng sa ho ikatisa ha haploid.
