Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals.

Boron compounds are used in silica-based glasses and ceramics to give them resistance to thermal shock.

Boron compounds were known thousands of years ago.

Later ( 1925 ), deposits were found at Boron, California on the edge of the Mojave Desert.

After the borax mining and operations were moved from the Death Valley region to the Boron, California mine and facilities in 1927, the line relied upon whatever traffic could be found.

The company used the same logo, but with " Boron " as the brand name in other states.

) Boron and control rods are used to maintain primary system temperature at the desired point.

Boron carbide composites are today favoured for ceramic plates protecting against smaller projectiles, such as used in body armour and armoured helicopters ; this was in fact in the early sixties the first general application of ceramic armour.

Boron, phosphorus, silicon and carbon lower melting point and rapidly diffuse to base metals ; this allows diffusion brazing and allows the joint to be used above the brazing temperature.

Boron is an excellent neutron absorber ( and also undergoes some neutron scattering ) which decays into carbon or helium and produces virtually no gamma radiation, with boron carbide a commonly used shield where concrete would be cost prohibitive.

Boron nitride ( BN ) is used in Cubic boron nitride.

Boron carbide is used as a control rod material in both pressurized water reactors and boiling water reactors.

Boron is often used because its bond lengths are significantly shorter than that of other metals such as lithium, aluminium, or magnesium.

Boron, arsenic, phosphorus, and occasionally gallium are used to dope silicon.

Boron has been used in BPSG, the insulator in the interconnection layers of integrated circuits, particularly in the lowest one.

Several years later, Dr. Tanada * found that the electric charge is generated by the trace element boron, ( Boron has been used in solar cells to generate electricity ).

Boron was not recognized as an element until it was isolated by Sir Humphry Davy and by Joseph Louis Gay-Lussac and Louis Jacques Thénard.

Robert de Boron ( also spelled in the manuscripts " Bouron ", " Beron ") was a French poet of the late 12th and early 13th centuries who is most notable as the author of the poems Joseph d ' Arimathe and Merlin.

* in the late 12th or early 13th century, Robert de Boron associates the wizard Merlin with Brocéliande in his poem Merlin, also known as the Estoire de Merlin, or the Vulgate or Prose Merlin.

Boron and Graphite rods came around in 1970s after the 1960s when the United States and United Kingdoms invested considerable research into developing the new technologies.

The occurrence locale was the US Borax Mine at Boron in the western Mojave Desert.

Today, the town serves mainly as a bedroom community for those wishing to live near either Edwards Air Force Base or the U. S. Borax mine in Boron.

In the United States, one builder of modern, well-regarded double rifles in a variety of calibers is B. Searcy & Company of Boron, California.

A later author who took up the story, Robert de Boron, describes the history of the Grail in ancient times, and says the first Fisher King was a man called " Bron ".

Chrétien de Troyes wrote the first story of Perceval, le Conte du Graal ; Wolfram von Eschenbach's Parzival, Sir Thomas Malory's Le Morte d ' Arthur, and the now lost Perceval of Robert de Boron are other famous accounts of his adventures.

Robert de Boron is the first author to give the Holy Grail myth an explicitly Christian dimension.

The later development of the legends of the Holy Grail and Joseph of Arimathea by Robert de Boron interconnected these legends with Glastonbury and with Avalon an identification which also seems to be made in Perlesvaus.

The series concluded with the Beetleborgs gaining the enemy Boron as an ally, stripping Nukus of his greatest weapon ; and Les Fortunes made the decision to return willingly to Charterville prison, disabling Nukus ' ability to create new monsters out of illustrations.

The mule is honored at Benson, N.C. ( Sept. 22, 23 ) and at Boron, Calif. ( Sept. 24 thru Oct. 1 ), while the legend of the Maid of the Mist is celebrated at Niagara Falls through the 24th.

Boron () is a chemical element with chemical symbol B and atomic number 5.

Boron polymers and ceramics play specialized roles as high-strength lightweight structural and refractory materials.

Boron is essential to life.

Boron is similar to carbon in its capability to form stable covalently bonded molecular networks.

Boron carbide, B < sub > 4 </ sub > C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms.

Boron also forms other covalent carbides, e. g. B < sub > 25 </ sub > C.

Other authors had their own ideas: Robert de Boron portrayed it as the vessel of the Last Supper ; and Peredur had no Grail per se, presenting the hero instead with a platter containing his kinsman's bloody, severed head.

Though Chrétien ’ s account is the earliest and most influential of all Grail texts, it was in the work of Robert de Boron that the Grail truly became the " Holy Grail " and assumed the form most familiar to modern readers.

* The Didot Perceval, named after the manuscript ’ s former owner, and purportedly a prosification of Robert de Boron ’ s sequel to Joseph d ’ Arimathie.

Perceval, although unfinished, was particularly popular: four separate continuations of the poem appeared over the next half century, with the notion of the Grail and its quest being developed by other writers such as Robert de Boron, a fact that helped accelerate the decline of Arthur in continental romance.
