DescriptionECHEMI Editorial ReferenceBoron 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.Basic Info-

Liaoning PengDa technology Co., LTD., founded in 2004, is one of the few boron products processing enterprises in China. In 2010, under the strong support of the leaders of liaoning (yingkou) coastal industrial base, the company invested another 50 million yuan on the basis of its predecessor yingkou borda fine chemical industry co., LTD., built a new factory area of 7,100 square meters, and entered the metallurgical and chemical industry park of liaoning (yingkou) coastal industrial base through remote transformation. In 2017, boronda technology needs to continue to expand the production workshop of 2500 square meters and the inventory workshop of 1700 square meters due to the increase of customer supply. Relying on the abundant resource advantages and superior geographical location of boron resources in yingkou area, convenient transportation conditions, developed contacts and boron expert's long-term management philosophy of "quality first, integrity first", the company presents a dynamic development state.
