Boron is a chemical element. It has the symbol B and atomic number 5. In its crystalline form it is a brittle, dark, lustrous metalloid; in its amorphous form it is a brown powder. As the lightest element of the boron group it has three valence electrons for forming covalent bonds, resulting in many compounds such as boric acid, the mineral sodium borate, and the ultra-hard crystals of boron carbide and boron nitride.

2O. It is a colorless to white mineral crystallizing in the monoclinic crystal system typically occurring as prismatic to acicular crystals or granular masses. It is relatively soft with Mohs hardness of 2.5 to 3 and light with a specific gravity of 1.91. It exhibits perfect cleavage and a brittle fracture.
Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula B(OH)3. It may also be called hydrogen orthoborate, trihydroxidoboron or boracic acid. It is usually encountered as colorless crystals or a white powder, that dissolves in water, and occurs in nature as the mineral sassolite. It is a weak acid that yields various borate anions and salts, and can react with alcohols to form borate esters.
A borate is any of a range of boron oxyanions, anions containing boron and oxygen, such as orthoborate BO3−3, metaborate BO−2, or tetraborate B4O2−7; or any salt of such anions, such as sodium metaborate, Na+[BO2]− and borax (Na+)2[B4O7]2−. The name also refers to esters of such anions, such as trimethyl borate B(OCH3)3 but they are alkoxides.
Borax (also referred to as sodium borate, tincal and tincar ) is a salt (ionic compound), a hydrated or anhydrous borate of sodium, with the chemical formula Na2H20B4O17 (also written as Na2B4O7·10H2O).
Boron is a census-designated place (CDP) in Kern County, California, United States. Boron is 15 miles (24 km) southwest of Red Rock Mountain at an elevation of 2,467 feet (752 m). The population was 2,086 at the 2020 census, up from 2,025 at the 2000 census. Boron is named after the element boron and is the site of the world's largest source of the boron compound boric acid.
Boron deficiency is a common deficiency of the micronutrient boron in plants. It is the most widespread micronutrient deficiency around the world and causes large losses in crop production and crop quality. Boron deficiency affects vegetative and reproductive growth of plants, resulting in inhibition of cell expansion, death of meristem, and reduced fertility.
Outokumpu is a town and municipality of Finland. It is located in the North Karelia region, 48 kilometres (30 mi) west of Joensuu and 92 kilometres (57 mi) east of Kuopio. The municipality has a population of 6,416 and covers an area of 584.05 square kilometres (225.50 sq mi) of which 138.22 km2 (53.37 sq mi) is water. The population density is 14.39 inhabitants per square kilometre (37.3/sq mi). The most important road connection in the locality is Highway 9.
Colemanite (Ca2B6O11·5H2O) or (CaB3O4(OH)3·H2O) is a borate mineral found in evaporite deposits of alkaline lacustrine environments. Colemanite is a secondary mineral that forms by alteration of borax and ulexite.
Boliden AB is a Swedish multinational metals, mining, and smelting company headquartered in Stockholm. The company produces zinc, copper, lead, nickel, silver, and gold, with operations in Sweden, Finland, Norway, and Ireland.
The Borate Minerals are minerals which contain a borate anion group. The borate (BO3) units may be polymerised similar to the SiO4 unit of the silicate mineral class. This results in B2O5, B3O6, B2O4 anions as well as more complex structures which include hydroxide or halogen anions. The [B(O,OH)4]− anion exists as well.
20 Mule Team Borax is a brand of cleaner manufactured in the United States by The Dial Corporation, a subsidiary of Henkel. The product primarily consists of borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, and is named after the 20-mule teams that were used by William Tell Coleman's company to move borax out of Death Valley, California, to the nearest rail spur between 1883 and 1889.
Francis Marion Smith was an American miner, business magnate and civic builder in the Mojave Desert, the San Francisco Bay Area, and Oakland, California. He was known nationally and internationally as "Borax Smith" and "The Borax King", as his company produced the popular 20-Mule-Team Borax brand of household cleaner.
The Pacific Coast Borax Company (PCB) was a United States mining company founded in 1890 by the American borax magnate Francis Smith, the "Borax King".
Boron compounds are compounds containing the element boron. In the most familiar compounds, boron has the formal oxidation state +3. These include oxides, sulfides, nitrides, and halides.
Disodium octaborate is a borate of sodium, a chemical compound of sodium, boron, and oxygen — a salt with elemental formula Na2B8O13 or (Na+)2[B8O13]2−, also written as Na2O·4B2O3. It is a colorless crystalline solid, soluble in water.

Borax Lake is a 10-acre (4.0 ha) alkaline lake in the Alvord Desert of southeastern Oregon in the United States. The lake is fed by geothermal springs 100 feet (30 m) below the surface that range in temperature from 104 to 300 °F. Surface water temperatures usually range from 61 to 100 °F but occasionally go higher. The springs lie along the Steens fault zone, which runs north–south through the Alvord Valley east of Steens Mountain.
The Rio Tinto Boron Mine in Boron, California is California's largest open-pit mine and the largest borax mine in the world, producing nearly half the world's borates. Ore reserves are sufficient for current economic production through early 2040's. It is operated by the Borax division of the Rio Tinto Group.
