What is Amorphous Boron Powder? Amorphous Boron Powder is relatively active, tasteless, odorless, stable in air and at room temperature, heated to 300 ℃, oxidized, and burned when reaching 700 ℃. The flame is red when burning, and the boron flame of trace gasification is green. The element boron is insoluble in water, hydrochloric acid, ethanol, ether, sulfuric acid, nitric acid, and molten metal but soluble in the cold concentrated alkaline solution and decomposed into hydrogen, which is oxidized to boric acid by concentrated nitric acid and concentrated sulfuric acid At high temperatures, boron can interact with oxygen, nitrogen, sulfur, halogens, and carbon. Boron can also be directly combined with many metals to form metal compounds. It can also react with organic compounds to form compounds that combine boron directly with carbon or compounds with oxygen between boron and carbon Monomer boron is at a particular position in the periodic table that divides elements into metal and nonmetal boundary colors. It is a nonmetallic element with vital negative electricity, a small atomic radius, total nuclear charges, and similar nonmetallic properties to silicon. Its density is 2.35g/cm3. Its hardness is 9.3, specific gravity is 2.33-2.45, melting point is 2300 ℃, and boiling point is 2550 ℃.
Application of Amorphous Boron Powder Amorphous simple boron is more active in chemical properties than simple crystalline boron, and crystalline boron is very hard. It is often used to replace diamonds to make cutting tools or drill bits. A small amount of boron is added in the process of metal smelting. On the one hand, it acts as a deoxidizer to prevent metal oxidation at high temperatures; on the other hand, it forms alloys to improve metal properties.
Properties of Amorphous Boron Powder Amorphous boron powder is a vital energy material. As a solid fuel in the composite solid propellant, the calorific value of boron is more than twice that of carbon, about twice that of aluminum, and more than that of magnesium. Its volumetric calorific value is almost three times that of hydrocarbon fuel, its density is slightly lower than that of aluminum, and it has the highest volumetric calorific value. As far as its energy is concerned, boron should be the best nonmetallic fuel. Moreover, the large specific surface area dramatically reduces the ignition temperature because of its irregular shape.
Harm of Amorphous Boron Powder to human body? Boron is highly toxic. It is forbidden to use as a food additive in many countries worldwide. However, our country has been accustomed to using Borax in food since ancient times. Borax is added to food to prevent corrosion, increase elasticity and expand Borax is very harmful to human health. The human body can naturally decompose many toxic substances and expel them from the body. However, after Borax enters the body, it will be converted into acid through the action of gastric acid, and boric acid is accumulated in the human body. Although the amount of Borax taken each time is small, it will get more. Continuous intake will collect in the body, which will hinder the role of digestive enzymes, cause anorexia, and indigestion, inhibit the absorption of nutrients, and promote fat decomposition; The acute poisoning symptoms are vomiting, diarrhea, red ground circulatory system disorder, shock coma, and another so-called boric acidosis. Boron in Borax can inhibit the DNA synthesis of bacteria and damage the human body's DNA.
Price of Amorphous Boron Powder Amorphous boron powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Amorphous Boron Powder. A large amount of large amount will be lower. The price of amorphous boron powder can be found on our company's official website.
