Give uses of boron and its compound.
Boron being extremely hard refractory solid of high melting point, low density and very low electrical conductivity, finds many applications. Boron fibres are used in making bullet-proovest and light composite material for aircraft.
The boron-10 $\left({ }^{10} \mathrm{~B}\right)$ isotope has high ability to absorb neutrons and therefore, metal borides
are used in nuclear industry as protective shields and control rods.
The main industrial application of borax and boric acid is in the manufacture of heat resistant glasses (e.g., Pyrex), glass-wool and fibre glass.
Borax is also used as a flux for soldering metals, for heat, scratch and stain resistant glazed coating to earthenwares and as constituent of medicinal soaps.
An aqueous solution of orthoboric acid is generally used as a mild antiseptic.
