Boron has until now only been known in the form of Natrium boratum (NaBO3) or Borax. We also know a little bit about Boric acid, (HBO3), but nothing is known about its homoeopathic properties in metallic form. It now appears that some of the key symptoms of Borax, namely the sensitivity to noise and the aggravation from downward motion, are in fact properties of the metal itself.
The name Boron is derived from Borax, the mineral that contains Boron in large quantities. Boron is a component of the gem stone tourmaline.
Boron looks more like carbon than like aluminium. Boron is the only element that can bond with another element into a structure of twenty equal-size planes, for instance in B12 H12. This structure of 20 planes is linked to the 5 equal-side plane structures and Boron is the 5th element in the periodic table. Like Carbon and Silicium it has a tendency to form long chains.
When Boron is mixed with steel it increases the tensile strength of the steel. Boroncarbide-BC- is very hard (9.9). Borax was often used in soap and water softeners.
In agriculture it is used in fertilisers and pesticides. Boron deficiency will cause hardening and dry rot in vegetables such as beetroot, and pitting in fruit such as apples.
