Soro, phyllo-, and cyclo- are prefixes referring to a class of minerals containing this element.
One compound containing this element with negative valence can be reacted with HCl to form a macromolecule named for Kautsky. Though it is not boron, Alfred Stock prepared several hydrides of this element. The first purifications of it were done by zone melting, which today is replaced by the Siemens and Schumacher processes. The Czochralski process creates most of the crystals of this element, which is tetra-methylated in a standard used in all NMRs. Soro, phyllo-, and cyclo- are prefixes referring to a class of minerals containing this element. It is the most common element to appear in integrated circuits and microchips and the second most abundant in the Earth's crust.
