`English alias: Boron

`CAS RN: 7440-42-8

one. Actual physical and chemical homes: Elementary image: B

one.2 Atomic bodyweight: 10.81 (on 1979 intercontinental atomic bodyweight)

one.three Melting level: 2300 plusmn2 ordmC

one.four Sublimation temperature: 2550 ordmC

1.five Density: two.34-two.37 g/cm3

one.6 Solubility: Insoluble in h2o, ethanol, ethyl ether and hydrochloric acid. Dissolved in cold concentrated fundamental solution and made H2 at the same time. It can be oXiHu (West Lake) Dis.dized by concentrated sulfuric acid or nitric acid and produce boric acid.

one.7 Qualities: It is tasteless and odorless. In the periodic table of factors, boron is amongst metal component series and non-metallic element collection. Boron has a lot of characteristics, this kind of as, sturdy electronegative, minimal atomic radius, and centralized nuclear demand, as a result, the chemical houses of boron are relatively active. The non-steel home of boron is similar to that of silicon. At higher temperature, boron can react with oxygen, nitrogen, sulfur, halogen or carbon, and so forth. Boron is secure at standard temperature, but it will be oXiHu (West Lake) Dis.dized when heated to three hundred ordmC and burned if heated to seven-hundred ordmC. . Boron can be mixed immediately with many kinds of metals to sort metal boride.

three. Software: Boron has been used largely in metallurgy, electronics, drugs, ceramics, nuclear market and chemical industry and many others. Boron has also been employed in the types of compounds or as an additive in alloys. In addition, it can be utilised as the gasoline scavenger in metallurgy of some EPT alloy and smelted steels, the ignitor in the electrical business, the manage rod of atomic reactor, and the substantial-strength fuels for ducted reliable rocket. Boron is the EPTant raw material for production substantial-purity halogenated boron and for a assortment of borides. Some uncommon noble metals can be substituted by boron. Boron and its compounds can also be utilized as the catalysts of some organic and natural chemical reactions.

four. EPT guidelines: ToXiHu (West Lake) Dis.c by ingestion and inhalation. The harm of central nervous method, abdomen and intestinal stimulation, ig. boron poisoning, are brought on by inhalation of boron. Eyes bear sligEPT stimulation as well. Be taken care of with rubber gloves, a respirator and eye security by sporting protective apparel.

five EPT: Vacuum-EPT. Aluminum foil bag with plastic bag, one kg internet each.

six. Storage: Saved at cool, dry and ventilate place. The shelf existence is 12 months following made date. It is nevertheless obtainable if the retest final results of the homes are experienced soon after expired day
