Physical and chemical properties.

Executive standard: Q/YTY002-2022

English alias: Boron

CAS RN: 7440-42-8

1. Physical and chemical properties：

1.1 Elementary symbol: B

1.2 Atomic weight: 10.81 (on 1979 international atomic weight)

1.3 Melting point: 2300±2℃

1.4 Sublimation temperature: 2550℃

1.5 Specific gravity: 2.34-2.37

1.6 Solubility: Insoluble in water,ethyl ether and acid. Dissolved in cold concentrated basic solution and produced H₂ at the same time. It can be oxidized by concentrated produce boric acid.

1.7 Properties: It is tasteless and odorless. In the periodic table of elements, boron is between metal element series and non-metal element series. Boron has many characteristics, such as, strong electronegative, low atomic radius, and centralized nuclear charge, therefore, the chemical properties of boron are relatively active. The non-metal property of boron is similar to that of silicon. At high temperature, boron can react with oxygen, sulfur, halogen or carbon, etc. Boron is stable at normal temperature. but it will be oxidized when heated to 300℃and burned if heated to 700℃. Boron can be combined directly with many sorts of metals to form metal boride.

ECHEMI Editorial Reference

Boron is a trivalent, nonmetallic element that occurs abundantly in the evaporite ores, borax and ulexite. Boron is never found as a free element on Earth. Boron as a crystalline is a very hard, black material with a high melting point, and exists in many polymorphs. Boron has several forms, the most common form being amorphous boron, a dark powder, non-reactive to oxygen, water, acids, and alkalis. It reacts with metals to form borides. Boron is an essential plant micronutrient. Sodium borate
DryPowder; OtherSolid
Boron is a compound that occurs in nature. It is often found combined with other substances to form compounds called borates. Common borate compounds include boric acid, salts of borates, and boron oxide. Several companies in the United States produce most of the world's borates by processing boron compounds. Borates are used mostly to produce glass. They are also used in fire retardants, leather tanning industries, cosmetics, photographic materials, soaps and cleaners, and for high-energy fuel. Some pesticides used for cockroach control and some wood preservatives also contain borates.|Boron atom is a nonmetal atom, a boron group element atom and a metalloid atom. It has a role as a micronutrient.|Boron (B) is a chemical element with an atomic number 5 that belongs in the Period 2 and Group 13 in the periodic table. It is a low-abundant metalloid that is a poor electrical conductor at room temperature. Natural boron exists in 2 stable isotopes however pure boron is hard to prepare due to contamination by different elements. It is also found for applications including ceramics, high-hardness or abrasive compounds, metal coatings, detergents, bleaching agents, insecticides, semiconductors, magnets, wood preservatives, and an additive in glass fibers of boron-containing fiberglass for insulation and structural materials. Boric acid contains antiseptic, antifungal, and antiviral properties thus it is used as a water clarifier in swimming pool water treatment. There are few pharmaceutical agents that contain a boron molecule in their structures, such as [DB09041] and [DB00188].|Boron is an element with atomic symbol B, atomic number 5, and atomic weight 11.|A trace element with the atomic symbol B, atomic number 5, and atomic weight [10.806; 10.821]. Boron-10, an isotope of boron, is used as a neutron absorber in BORON NEUTRON CAPTURE THERAPY.
