Property:
Borax looks like white crystal or glass. The melting point of oc rhome crystal is at 742.5°C with the density of 2.28. The meliting point of β rhomic crystal is at 664°C, with the denstity of 2.75. Anydrous Borax has the property of moisture absorption. Borax is not only dissolving in water, but also dissoves slowly in methanol to from a solution with the 13-16% contents of boron. The technical norm is Borax.
