Strontium boride appears as a crystalline black
powder. Closer examination reveals slightly translucent
dark red crystals capable of scratching quartz. It is very
stable and has a high melting point and density.
Although not thought to be toxic, it is an irritant to the
skin, eyes, and respiratory tract. It has the formula of
SrB6, with a molecular weight of 152.49 g/mol. It is
a black crystalline solid (15.0 °C) with a density of
3.39 g/cm3, and a melting point of 2235.0°C.
Strontium boride, along with other alkali earth metal
borides, has been shown to exhibit weak ferromagnetism
at low temperatures. | [Uses]
Strontium boride is used in insulation
and nuclear control rods. | [Preparation]
Strontium boride can be formed directly from the
elements. Sr melts at 777°C and boron melts at
2076 °C. Therefore, if a vapor of Sr metal at >850°C
(red-heat) is passed over crystals of boron, reaction
forms the desired boride. However, to obtain stoichiometric
compositions, it is better to heat the well-mixed
powders of Sr and B to obtain specific compounds:
