Is boron a metal?Boron powder does not belong to the metal family, and it is a solid that lacks many of the metal's characteristics. Boron has the lowest outermost electron count of any non-metallic. It is available in both crystalline and amorphous forms. The crystalline form is either black-black or brown-black powder. 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 degrees C. Even after long boiling, hydrofluoric or hydrochloric acids will not ignite boron.
Boron is slowly oxidized and eroded when a mixture of concentrated nitric and dichromate sodium and sulfuric acid is heated. The boron crystals can be slowly oxidized by hydrogen peroxide or ammonium perisulfate. Boron reacts violently and rapidly with sulfur when heated to 600 deg C. A mixture of boronsulfide is formed. The boron nitride occurs when the boron temperature is raised 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 is oxidized by air, the boron film forms, which prevents the boron inside from oxidizing further. It is stable at room temperature, and does not react with hydrochloric or hydrofluoric aqueous acid. Boron powder is soluble with sulfuric acid and boiling nitric, but not in water. Amorphous boron has a chemically active nature, and the powder can be combined with air to form explosive mixtures.
Boron is an electrical conductor that is weak at normal temperature but good at higher temperatures. The elemental form of boron comes in different allotropes. Amorphous is brown and crystalline 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. Amorphous and crystalline boron are 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 ribonucleic-acid formation. Ribonucleic-acid is an important component of 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 as 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 containing boron and elemental Boron. Also, it is used for metallurgy. Building materials, electrical, chemical and light wool industries. Pharmaceutical, agricultural, and nuclear industries. 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 a variety borides. This can replace valuable metals and olefin deficient metals.
