What is Borides Powder?
The boron is combined with metals or non-metals. It is usually a mesenchymal substance and does not conform to 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. 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 with the transition metals. The compounds with high melting point are formed from elements in groups IVA and VA. 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 Powders TiB2, ZrB2, or HfB2 are the most stable.
Boride Powder crystal structure
Between boron atoms, the lattice forms structural units that include single bonds and double bonds. Also, spatial frameworks such as networks are created. As the proportion of boron increases in the boride, the structure unit becomes more complex.
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 the 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
Reducing metal oxide and boric acid with carbon is
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
Reduce refractory metal oxides by using boron
Borides Powder: Use and nature
Boride is known for its high conductivity. It also has a high melting temperature, high hardness and high stability. The oxidation resistance at high temperatures of boride metals 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 mainly metals with high conductivity, positive temperature coefficient of resistence and a metallic appearance. Borides Powders Ti, Zr, Hf, and Zr have better conductivity compared to their metals.
The creep resistance is excellent, which makes it a good choice for materials used in gas turbines or rockets. They can also resist deformation and corrosion and are resistant to heat shock. Borides Powder, carbides, nitrides, or other alloys or cermets can be used as sample holders for high temperature material testing machines and instruments, bearings, structural parts for nuclear energy devices, and components for aviation equipment.
