Izakhiwo ze-anhydrous borax amakristalu amhlophe noma amakristalu engilazi angenambala, indawo encibilikayo ye-α orthorhombic crystal ingu-742.5 ° C, kanti ukuminyana kungu-2.28;Ine-hygroscopicity eqinile, incibilika emanzini, i-glycerin, futhi incibilika kancane ku-methanol ukuze yakhe isixazululo nge-concentration ye-13-16%.Isixazululo saso esinamanzi sine-alkaline ebuthakathaka futhi asincibiliki otshwaleni.I-anhydrous borax iwumkhiqizo ongenamanzi otholakala lapho i-borax ishisiswe ibe ngu-350-400°C.Uma ibekwe emoyeni, ingakwazi ukumunca umswakama ku-borax decahydrate noma i-borax pentahydrate.
