Is Boron a metal or non-metal Whats The Boron Properties and Boron Uses
Is boron a metal?Boron powder does not belong to the metal family, nor does boron as a solid. It lacks many of the properties that metals have. Boron has the lowest outermost electron count of any non-metallic. It is available in both amorphous (like sand) and crystalline form. The first form is brown-black powder to black, while the second is black-black or silver-gray with a metallic sheen. It has a hardness similar to that of diamond. Amorphous Boron slowly oxidizes at room temperature in the air, and it self-ignites around 800 degC. Boron, hydrochloric and hydrofluoric acids do not react even after they have been boiled.
Boron is slowly eroded and oxided by a hot mixture of sodium dichromate with sulfuric acid. The crystalline boron can be oxidized by hydrogen peroxide or ammonium sulfate. Boron reacts violently and rapidly with sulfur when heated to 600 deg C. A mixture of boronsulfide is formed. Boron nitride can be formed when boron in ammonia or nitrogen is heated above 1000 degrees C. At 1800-2100 deg C hydrogen and boron don't react. But at 2100 deg C and higher, boron, silicon, and ammonia react to form silicon-boride. At high temperature, boron can react with metals and metal oxides in order to produce metal borides.
It is a dark-brown or black powder. When it oxidizes in air, the boron film prevents the internal element from oxidizing. It reacts at normal temperatures with fluorine and is uncorroded by hydrochloric or hydrofluoric aqueous acid solutions. Boron powder is soluble with sulfuric acid and boiling nitric, but not in water. Amorphous boron has a chemical activity, and the powder can be explosive when mixed with air.
Boron is an electrical conductor that is weak at normal temperatures and strong at higher temperatures. The elemental form of boron comes in different allotropes. The amorphous form is a powdery brown color, while the crystalline form is grayish black. Elemental Boron has a hardness that is similar to diamond. It also has a very high electrical resistance. But its electrical conductivity will increase with temperature. Crystalline boron tends to be more inert while amorphous is more active. The stable isotopes of boron are only two. Boric acid and borate are the main forms of boron in nature.
Boron is essential for the production of ribonucleic Acid, an important component in life. James Stephenson is a postdoctoral scientist at the University of Hawaii NASA Institute of Astrobiology. He said: "Bronze could be important for life's origin on Earth, because it stabilises nucleics, which are key components of the ribonucleic. Ribonucleic acids are considered to be precursors of DNA information in the early stages of life.
Boron is an important chemical raw-material mineral. It is used primarily in the productions of borax and boric acid, as well as for the compounds and elemental borons. Also, it is used for metallurgy. Building materials, machinery and electrical industries. Chemicals, light wools, pharmaceuticals, agricultural products, and more. Boron is a very important material that can be added to an alloy as a component or as an additive.
Boron is an important raw material in the manufacture of high purity boron halides. It can also be used for the smelting and igniting of special alloys steels in the electronics sector, control rods in rocket reactors or rocket high energy fuels. Boron is used as a raw material to make borides. This powder can be substituted for valuable metals and can reduce the amount of these metals.
