Before the introduction of Gooch's process it was usual to determine the boron trioxide "by difference."
With an unstable fuel like boron hydride, that made the difference.
When heated to low redness it decomposes into free iodine and phosphide of boron, BP.
boron was discovered in various parts of the hop plant—in the clusters, leaves, pedicels, and stems.
Some consider it a regular metal, but it is usually called a "hyalogen" or glass former like boron.
Increase of the strength of boron raises the toxicity until 1/1000 practically inhibits increase in dry substance.
There is only one series of boron compounds which have any importance.
The boron was found to be fairly evenly distributed through sound and affected organs.
Silicon and boron are not attacked by acids under ordinary conditions; titanium is easily dissolved by them.
After three months growth the plants were harvested, when those with most boron were found to have died after making about 10 cm.
boron bo·ron (bôr'ŏn')
A soft, amorphous or crystalline nonmetallic element, used in flares and nuclear reactor control rods. Atomic number 5; atomic weight 10.811; melting point 2,075°C; sublimation point 2,550°C; specific gravity (crystal) 2.34; valence 3.
A shiny, brittle, black metalloid element extracted chiefly from borax. It is a good electrical conductor at high temperatures and a poor conductor at low temperatures. Boron is necessary for the growth of land plants and is used in the preparation of soaps, abrasives, and hard alloys. It is also used in the control rods of nuclear reactors as a neutron absorber. Atomic number 5; atomic weight 10.811; melting point 2,300°C; sublimation point 2,550°C; specific gravity (crystal) 2.34; valence 3. See Periodic Table.
