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

`English alias: Boron

`CAS RN: 7440-forty two-eight

1. Bodily and chemical properties:

1.1 Elementary image: B

1.two Atomic weight: 10.81 (on 1979 international atomic weight)

1.3 Melting stage: 2300 plusmn2 ordmC

1.4 Sublimation temperature: 2550 ordmC

one.five Density: two.34-two.37 g/cmthree

one.six Solubility: Insoluble in water, ethanol, ethyl ether and hydrochloric acid. Dissolved in cold concentrated standard resolution and created Htwo at the very same time. It can be oXiHu (West Lake) Dis.dized by concentrated sulfuric acid or nitric acid and produce boric acid.

1.7 Qualities: It is tasteless and odorless. In the periodic table of aspects, boron is amongst metallic element sequence and non-metal element collection. Boron has many characteristics, these kinds of as, robust electronegative, lower atomic radius, and centralized nuclear charge, as a result, the chemical qualities of boron are relatively energetic. The non-steel house of boron is related to that of silicon. At higher temperature, boron can respond 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 300 ordmC and burned if heated to 700 ordmC. . Boron can be mixed straight with numerous types of metals to form metal boride.

three. Application: Boron has been utilised mainly in metallurgy, electronics, drugs, ceramics, nuclear market and chemical industry and so forth. Boron has also been utilized in the forms of compounds or as an additive in alloys. In addition, it can be utilised as the gas scavenger in metallurgy of some EPT alloy and smelted steels, the ignitor in the electrical business, the management rod of atomic reactor, and the higher-vitality fuels for ducted sound rocket. Boron is the EPTant uncooked materials for production higher-purity halogenated boron and for a range of borides. Some exceptional noble metals can be substituted by boron. Boron and its compounds can also be employed as the catalysts of some organic and natural chemical reactions.

4. EPT recommendations: ToXiHu (West Lake) Dis.c by ingestion and inhalation. The injury of central nervous program, abdomen and intestinal stimulation, ig. boron poisoning, are induced by inhalation of boron. Eyes bear sligEPT stimulation as effectively. Be managed with rubber gloves, a respirator and eye security by putting on protecting clothing.

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

6. Storage: Stored at awesome, dry and ventilate spot. The shelf lifestyle is twelve months following created date. It is even now available if the retest results of the qualities are qualified after expired date

seven. Transportation:Keep away from rain, sunligEPT and crash. Do not blend with strong oXiHu (West Lake) Dis.dizer.
