_____________
Action of metals
_____________
Except for Cu, Ag and Au, Boron combines with other metals at high temperatures to form borides. These borides are extremely hard substances. Mg3B2 and Be3B2 are attacked by acids to form boron hydrides.
_________________
Action Of Non Metals
_________________
Boron also reacts with non-metals. For example: Boron combines with N2 at temperatures greater than 900 C to form boron nitride, BN. Boron forms boron sulphide B2S3 when heated with S. On heating with Carbon in an electric furnace an extremely hard substance namely boron carbide, B4C is formed.
_____________
Action Of Steam
_____________
Boron reacts with steam at red heat liberating H2.
2B + 3H2O → B2O3 + 3H2
