Boron Wikipedia

Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth's crust. It constitutes about 0.001 percent by weight of Earth's crust. Boron is concentrated on Earth by the water-solubility of its more common naturally occurring

Cubic Boron Nitride an overview ScienceDirect Topics

Cubic boron nitride. Polycrystalline cubic boron nitride (PCBN) was originally developed for the turning and machining of tool steels, cast irons and super alloys [3, 71]. Recently, PCBN has gained acceptance as a friction stir tool material, especially for high-temperature alloys [3].

Ulexite Wikipedia

Ulexite is a structurally complex mineral, with a basic structure containing chains of sodium, water and hydroxide octahedra. The chains are linked together by calcium, water, hydroxide and oxygen polyhedra and massive boron units. The boron units have a formula of [B 5 O 6 (OH) 6] 3– and a charge of −3. They are composed of three borate tetrahedra and two borate triangular groups.

Positive Health Online Article Boron: Major Cause and

Forty years ago, Dr Rex Newnham developed arthritis, and orthodox medicine did not help. His analysis of the differences between the fertility of clay soil and sandy soil (sandy soil showed mineral deficiencies) led him to look at the connection between mineral deficiencies and arthritis. One of the minerals deficient in the soil was boron, which is needed in the green plant for proper usage

The biological effects of boron are dose-dependent but follow a U-shaped pattern, rendering it important to define the active range. The studies of Bahadoran et al. on rats and Naghii et al. on humans showed that low doses of boron (3 and 10 mg/day) prevented kidney stone formation. The aim of this study was to determine whether high doses of

Boron species other than B(OH)3 and B(OH)4- can be ignored for most practical purposes in soils. Boron is specifically adsorbed to clay minerals, hydrous metal oxides, and organic matter in soils. Boron can also be coprecipitated with calcium carbonate. In low B soils, a large portion of total B is associated with the organic matter.
