硼(b)醋酸酐、硼氧化二氮

Boron Oxide(Superfine)Molecular Formula B2O3 Molecular Weight 69.62 Boron Oxide(B2O3) ≥99% Characteristic Boron Oxide,also known as Diboron tridoxide ,is a colourless or white crystal powser.The melting point is at 450°C,with the density of 1.085g/ml.It is odourless and looks creamy. If left exposed in the air,Boron Oxide absorbs water intensively to form Boric Acid .At higt temperature,it can be reducted into single element Boron by Alkali metal, Magnesium or Alumininm.Baron Oxide is soluable easily in acids,ethanol,hot water,but slightly soluable in cole water.It combines with metals to form boron glasses whit specific colours,and it dissoves with the alkali and oxisized metals such as copper ,silver,aluminium,tin and arsenide.
