What is Borides Powder?
Boride Poudre
The boron is combined with metals or non-metals. It is usually a mesenchymal material and does follow valence rules. 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. They are chemically inert and cannot be dissolvable by hot concentrated acid. They can be combined directly with elements, or by reducing oxides and active metals. They can be used as superconducting, refractory and abrasive materials.
Boron, a light metal, forms Borides Powder with the transition metals. The compounds with high melting point are formed from elements in groups IVA and VA. The structural properties of the boron element determine the boride crystal structure. Borides Powder’s chemical stability gradually decreases as it moves from IVA towards VIA. Borides Powders TiB2, ZrB2, or HfB2 are the most stable.
Boride Powder crystal structure
Between boron atoms, a lattice of borides is formed. This lattice contains structural units that are single bonds or double bonds as well as networks and spatial frames. The more boron is present in the boride, the more complex the structure unit.
In general, the more complex an atom’s structure is, the less likely that it will be hydrolyzed. Its resistance to oxidation or nitridation increases.
In transition metal Borides Powder the chemical bond is between the metal and the boron. This electronic bond transforms the boron into a positively-charged ion.
Borides Powder: Preparation methods
Borides Powders are made in a number of ways.
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, magnesium reduces the oxides to generate metals and boron.
MeO + B2O3 + AI (Si,Mg )—MeB+Al oxide
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’s thermal stability is also good because it has high thermal 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 do dissolve in nitric. Borides Powders are a mixture of metals and plastics. They have high conductivity, and a positive coefficient of thermal 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 based alloys or Cermets can be used in the manufacture of rocket structural components.
