Metal borides can be defined as hard compounds that are formed from transition metals and/or boron. Boride crystal structures are determined by the structural characteristics boron-atoms. Slowly, the chemical stability decreases in the order IVA to VIA. HfB2, ZrB2, TiB2, ZrB2, etc. are the most stable borides.
Borides attributes
Borides crystals have a very high melting point as well as hardness. It cannot be broken down by boiling concentrated nitric or hot water. This can either be made by the direct compounding or by adding active metals as reducing oxides.
Borides have a hardness similar to those of carbides. However, some borides can be slightly more. Because borides have a higher covalently bond than carbide, this is why they are harder to work with. Borides, however, are very brittle and have strong inertness. They are therefore used in specific fields.
Boride features high conductivity, high melting points, and high stability. Boride can be compared to Group IVB metals Boride for its oxidation resistance.
Molybden alkali can dissolve borides. Moist air and dilute hydrochloric Acid are not effective against borates of alkaline Earth metals or rare earths. However, nitric acids can dissolve them. Borides almost all have similar properties to metals with high conductances and positive temperatures coefficients of resistance. Ti, Zr, Hf borides have a higher conductivity than the metals.
Borides app
Borides can be used for a number of purposes in the textile sector. It can be used for high-efficiency resin finishing catalysts and as flame retardant in flame retardant finishing. It is an indispensable raw material for the manufacture of detergents, photo equipment and electroplating.
Statisticians have shown that the proportion of daily-use glasses, daily use enamel, light bulbs and other light industrial sector consumptions of borax, boric acid, and light bulbs accounted for 35.30% and 39.2%, respectively, of all the 1990s consumptions. The consumption rate in the glass- and ceramics industries reached 71% by the end of the 21st centuries.
There was a total of 31,700 tonnes consumed in soap washing and bleaching. 8.97% was spent on soap. Glass, ceramics and enamel were used in Japan for 59,000 tons. Cleaning and bleaching was also used at 1 million tons.
Detergents, soaps, personal care and other products accounted 15% of global borate market consumption at the turn of the 21st-century.
Boride is strong in creep resistance. This is important when working with gas turbines or rockets. Borides and carbides can be combined to make various alloys or compounds. They are also used in the manufacture of rocket and aviation component components.
Calcium boreide properties:
Calcium boride is known for its high melting point, high hardness and other characteristics. Calcium boride is very stable in both chemical and physical terms. Air calcination will result in sub-micron CaB6 gaining weight at 800°C. It is also difficult to oxidize. CaB6 cannot be easily dissolved in both hydrochloric and sulfuric acids. Technically, you can remove impurities with hot hydrochloric material, but CaB6 will dissolve in nitric.
Calcium hexaboride are dark gray powders or granules. It is non-soluble in water, having a melting temperature of 2230°C and a relative density 2.33g/cm2.
Silicon boride (a shiny, dark-gray powder) has a relative densit of 3.0g/cm with a melting point at 2200°C. They are insoluble when mixed with water.
Main application of calcium boride:
1. Calcium Boride is used to add boron in dolomite coal and magnesium dolomite carbon refractories. It resists oxidation, erosion and increases thermal strength.
2. This is used as a deoxidizing or degassing agent to enhance conductivity and strength of highly conductive red-colored copper.
3. This material is used as an innovative type of material to stop neutrons being released into the nuclear industry.
4. This material is used as a semiconductor material for new spin electronic components at temperatures of 900K.
5. This is used to produce boron trichloride (BCl3) as well as amorphousboron.
6. This is used to produce high-purity metal borids (TiB2, ZrB2, FfB2, etc.). and high-purity, boron alloys, such as Ni-B (Co-B), Cu-B (etc.). ).
7. This calcium boride can be used to create a mix of the catalyst (Ca3B2N4), hexagonal boron-nitride and a crystal cubic boron. It also produces a high performance, extremely stable boron.
8. Useful for deoxidation and desulfurization.
9. It is used for deoxygenation and desulfurization.
10. Used to deoxidize metal smelting.
