What is boron used for?
The most common form of boron is the compound borax, used for a
variety of purposes ranging from cleaning and antiseptics to making
glass and enamel. There is a new procedure called boron neutron
capture therapy (BNCT) to target cancer cells. Boron is attracted
to cancer cells. It is also used in glass and ceramics and is a
essential plant nutrient. In the nuclear power industry, boron is
useful to absorb thermal neutrons very strongly, so it is used in
control rods and sometimes as a soluble insect poison.
