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