What is Borides Powder?
Boride Poudre
The boron is combined with metals or non-metals. It is usually a mesenchymal material and does follow the valence laws. Except for zinc (Zn), cadmium (Cd), mercury (Hg), gallium (Ga), indium (In), thallium (Tl), germanium (Ge), tin (Sn), lead (Pb), bismuth (Bi).
Borides powder can be formed from other metals. These crystals are hard and have melting points. Chemically stable, they cannot be dissolved with hot concentrated nitric. They can be combined directly with elements, or by reducing oxides and active metals. They can be used as superconducting, abrasive and refractory materials.
Boron, a light metal, forms Borides Powder stable with transitional metals. The compounds with the highest melting points are formed from elements in groups IVA and VA or VIA. The structural characteristics of the boric atom determine the crystallographic structure of boride. Borides Powder’s chemical stability gradually decreases as it moves from IVA towards VIA. Borides Powder TiB2, ZrB2, or HfB2 are the most stable.
Boride Powder crystal structure
Between boron atoms, single bonds, dual bonds, networks and spatial frames are formed in the boride structure. The more boron is present in a boride, the more complex the structure unit.
In general, the more complex boron’s atomic structure, the less likely boron is to be hydrolyzed. It also has a stronger resistance to oxidation and nitrogen.
In transition metal Borides Powder the chemical bond is between the metal and boron. This electronic bond transforms the boron into a positively-charged ion.
Borides Powder: Preparation methods
Borides Powders are made by the main method of refractory metal Borides powder manufacturing.
1. The reaction formula between metal and boron at high temperature is
Me+B—-MeB
Reducing metal oxide and boric acid with carbon is
2MeO+B2O3+5C—2MeB+5CO
Aluminum (silicon, Magnesium) Thermal method. Aluminium or silicon or magnesium reduces the oxides to generate metals and boron.
MeB+Al oxide (Si or Mg
Reducing metal oxides by boron carburide and carbon
4MeO+B4C+3C—4MeB+4CO
Reduce refractory metal oxides by using boron
xMeO+2xB—xMeB+(BO)x
Borides Powder: Use and nature
Boride has high conductivity as well as high melting points, hardness and stability. Boride also has a relatively high thermal resistance and conductivity. The oxidation resistance at high temperatures of boride metal is based upon group IVB. Boride has the highest oxidation resistance.
Borides Powder do not react with humid air and dilute hydrochloric acids, but they are soluble with nitric. Borides Powders are a mixture of metals and plastics. They have high conductivity as well as a positive coefficient of temperature resistance. Borides Powders Ti, Zr, Hf, and Zr have better conductivity than the metals.
The creep resistance is excellent, which makes it a good choice for materials used in gas turbines or rockets. They can also resist corrosion and heat shock, while maintaining strength. Borides Powder, carbides and Nitrides can be combined to form cermets that are suitable for manufacturing rocket structural parts, aviation equipment components and turbine components. Sample holders for high temperature material testing machines and instruments, bearings for measuring high-temperature cone heads, structural parts for nuclear energy devices, etc.
