Product introduction

Boron has several allotropes, amorphous boron is also known as element boron, monomer boron. It is a brown powder or gray shiny crystal, chemical properties are more lively. Stable in air and room temperature. When heated to 300 ° C, it is oxidized and ignited at 700 ° C. The flame is red when burning, and the boron flame of trace gasification is green. Insoluble in water, hydrochloric acid, ethanol, ether. Can dissolve in the cold concentrated alkali solution and decompose the hydrogen gas, is oxidized to boric acid by concentrated nitric acid and concentrated sulfuric acid. Boron can interact with oxygen, nitrogen, sulfur, halogens and carbon at high temperatures. It can also combine directly with many metals to form borides. Boron reacts with organic compounds to produce compounds that are directly associated with boron and carbon, or that exist aerobically between boron and carbon.

In the periodic table, the monomer boron is in a special position to divide elements into metal and nonmetal, which is dominant in non-gold properties. Boron has strong electronegativity, small atomic radius, concentrated nuclear charge, and nonmetal properties similar to silicon. Its density is 2.35g/cm3. Hardness 9.3, specific gravity 2.33-2.45, melting point: 2300℃, boiling point: 2550℃.
