The metal borides are hard substances made of transition metals like boron. The properties of boron molecules determine the structure of boride. Gradually, the chemical strength of the boride drops in order from IVA up to VIA. HfB2 and ZrB2 have the highest chemical stability.
The Borides Characteristics:
Borides can be described as a crystal having a high level of hardness or melting point. It is chemically solid and cannot dissolve in hot concentrated nitric. It is possible to make it directly by compounding elements and by mixing reducing oxygens with active metallics.
Borides are similar in hardness to other carbides. Others may be slightly harder. Borides are much more covalently bound than carbide. Borides have some disadvantages, such as being fragile and having a high degree of inertness. However, they also possess strong chemical properties, which makes them useful in certain industries.
Boride is high in conductivity, melting point and hardness. Boride is also very strong, with a relatively high thermal conductivity. Boride’s high oxidation resistance at high temperature, based on Group IIVB metals Boride, is one of the best.
In molten alkali, borides can be dissolved. Borates from rare earth and other alkaline metals do not react with moist air. All borides are similar in appearance to metals. Most have high conductances and resistances to temperature changes. Ti, Zr & Hf’s borides exhibit a greater conductivity than those of their metals.
Borides are used extensively in textile manufacturing. Borides are used in a variety of applications, including as a high efficiency catalyst for resin-finishing and as a flame retardant to flame retardant coating. It is an integral raw material for electroplating, photography equipment, and detergents.
According to statistics, 35.30% and 39.2% respectively of the daily consumption in glass and enamel in the early 90s was borax.
8,97% of all soap was used to wash and bleach. In Japan, the number of glasses, ceramics, enamel and glass reached 59,000 tons. Bleaching and cleaning consumed 1 million tonnes.
Since the dawn of the 21st centuries, detergents/soaps and personal-care products have accounted to 15% of total global borate markets consumption.
Boride’s creep resistivity is excellent, which makes it an ideal material for use in rockets and gas turbines. Multiple alloys or cemets that contain borides (carbides), nitrides may be used to produce rocket structural components, aircraft device components, high temperature material testing machine sample holder holders and instrument parts, bearings and high-temperature coneheads for hardness, some structural elements of nuclear power device, etc.
Calcium Boride has high melting points and high hardness. It is stable both in chemical and physical aspects. When sub-micron CaB6 undergoes air calcination it will gain weight only at 800 degrees Celsius. Also, it is very difficult to oxidize. CaB6 doesn’t dissolve well in acidic sulfuric acid and hydrochloric. You can therefore remove impurities from hot hydrochloric. CaB6, however, dissolves in nitric.
Calcium Hexaboride has dark gray granules or powder. It has a melting temperature of 2230 ° C. The relative density is 2.33g/cm 2 and it is not soluble in water at normal temperatures (15 ° C).
Silicon boride, which is a glossy dark gray powder has a relative mass of 3.0g/cm. It also has a melting value of 2200 degrees C. They are insoluble and inert in water.
Calcium boride main use:
1. Calcium boride, which is a boron-containing addition to dolomite carbon and magnesium dolomitecharcoal, resists oxidation, erosion, as well as improves thermal strength.
2. To increase strength and conductivity by deoxidizing highly conductive red copper.
3. As a material that prevents neutrons from the nuclear industry, it is a novel type.
4. As a novel type of semiconductor material used in spin electronic component with temperature of 900K.
5. As a raw ingredient for the production of boron trichloride (BCl3) & amorphousboron.
6. As a raw materials for the production of high-purity boroides (TiB2, ZrB2,, HfB2, etc.). and high-purity alloys of boron (Ni-B. Co-B. Cu-B., etc. ).
7. Calcium boride helps to prepare a catalyst that includes calcium-boron trioxide (Ca3B2N4) or hexagonal, as well to obtain crystal cubic of boron nuitride.
8. As a deoxidizer, desulfurization or boron-increaser for boron alloy iron.
9. As a deoxygenator, desulfurization or boron increaser to boron steel.
10.Used to reduce the oxidizing effect of metal smelting.
