    Physical and chemical properties.

    Executive standard: Q/YTY002-2022

     Chinese name: 无定形元素硼

     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, ethanol, ethyl ether and hydrochloric acid. Dissolved in cold concentrated basic solution and produced H2 at the same time. It can be oxidized by concentrated sulfuric acid or nitric acid and 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, nitrogen, 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.

     3. Application:

    (1)Amorphous boron is used as high energy fuel for pyrotechnic systems. Target usage is key component of fuel-rich propellant system, energetic slurry, initiators, delayers

    (2) Boron has also been used in the forms of compounds or as an additive in alloys. In addition,

    (3) It can be used as the gas scavenger in metallurgy of some special alloy and smelted steels, the ignitor in the electric industry, the control rod of atomic reactor, and the high-energy fuels for ducted solid rocket.

    (4) Boron is the important raw material for manufacturing high-purity halogenated boron and for a variety of borides.

    (5) Some rare noble metals can be substituted by boron.

    (6) Boron and its compounds can also be used as the catalysts of some organic chemical reactions.


     4. Safety instructions:

    Toxic by ingestion and inhalation. The damage of central nervous system, stomach and intestinal stimulation, ig. boron poisoning, are caused by inhalation of boron. Eyes bear slight stimulation as well. Be handled with rubber gloves, a respirator and eye protection by wearing protective clothing.


     5 Packing:

    Vacuum-packaging. Aluminum foil bag with plastic bag, 500g net each.


     6. Storage:

    Stored at cool, dry and ventilate place. The shelf life is 12 months after manufactured date. After the storage period expires, the samples should be re-sampled and re-inspected according to the technical specifications in Part 2, and they can still be used after passing the test.


     7. Transportation:

    Avoid rain, sunlight and crash. Do not mix with strong oxidizer.

    In addition: We are able to develop custom-made products according to the clients’ requests
