High Purity ---- Make Ignitor Boron Powder CAS No 7440-42-8

Passivated / Amorphous Elemental Boron

`Executive stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd: Q/YTY002-2011

`English alias: Boron

`CAS RN: 7440-42-eight

1. Bodily and chemical homes:

one.1 Elementary symbol: B

one.two Atomic excess weight: 10.81 (on 1979 intercontinental atomic bodyweight)

one.3 Melting level: 2300 plusmn2 ordmC

1.four Sublimation temperature: 2550 ordmC

one.five Density: 2.34-two.37 g/cmthree

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

one.7 Homes: It is tasteless and odorless. In the periodic table of components, boron is among metallic element series and non-steel component series. Boron has a lot of qualities, this kind of as, robust electronegative, minimal atomic radius, and centralized nuclear cost, consequently, the chemical homes of boron are reasonably energetic. The non-metal property of boron is comparable to that of silicon. At substantial temperature, boron can react with oxygen, nitrogen, sulfur, halogen or carbon, and many others. Boron is stable at normal temperature, but it will be oXiHu (West Lake) Dis.dized when heated to 300 ordmC and burned if heated to 700 ordmC. . Boron can be mixed directly with a lot of kinds of metals to kind metal boride.

three. Software: Boron has been used mostly in metallurgy, electronics, drugs, ceramics, nuclear industry and chemical market etc. Boron has also been utilised in the varieties of compounds or as an additive in alloys. In addition, it can be utilized as the gasoline scavenger in metallurgy of some EPT alloy and smelted steels, the ignitor in the electric powered business, the manage rod of atomic reactor, and the higher-energy fuels for ducted sound rocket. Boron is the EPTant raw materials for production higher-purity halogenated boron and for a range of borides. Some unusual noble metals can be substituted by boron. Boron and its compounds can also be utilised as the catalysts of some natural chemical reactions.

four. EPT recommendations: ToXiHu (West Lake) Dis.c by ingestion and inhalation. The hurt of central nervous method, stomach and intestinal stimulation, ig. boron poisoning, are triggered by inhalation of boron. Eyes bear sligEPT stimulation as nicely. Be taken care of with rubber gloves, a respirator and eye security by wearing protective clothing.

five EPT: Vacuum-EPT. Aluminum foil bag with plastic bag, one kg net each and every.

6. Storage: Stored at cool, dry and ventilate location. The shelf lifestyle is 12 months soon after made date. It is nonetheless accessible if the retest final results of the homes are competent after expired date

seven. Transportation:Avoid rain, sunligEPT and crash. Do not mix with strong oXiHu (West Lake) Dis.dizer.
