Investigation on Characteristics And Application of Metal Borides And Calcium Boride

The metal borides are hard substances made of transition metals like boron. The structural characteristics boron-atoms have an impact on the crystal structure and stability of Boride. Gradually, the chemical strength of the Boride drops in order from IVA up to VIA. HfB2, ZrB2, TiB2, ZrB2, are the most stable.

The Borides Characters:

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. This is made possible by the combination of elements and reducing compounds with active minerals.

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 known for high heat conductivity, high melting temperature, and excellent stability. Boride is best compared with Group IVB metallic Boride because it has the greatest oxidation resistance.

In moltenalkali, borides can be dissolved. Borates from rare earths and alkaline minerals aren’t soluble or affected by moist water, dilute hydrogen chloric acid or humid air. But they can be dissolved in nitric. Borides of rare earth and alkaline metals have properties and conductivity similar to those of metals. Ti, Zr & Hf’s borides exhibit a greater conductivity than those of their metals.

Borides application:

Borides have many uses in the textile business. Borides are used in a variety of applications, including as a catalyst to improve resin finishing and as a flame retardant. It is an important raw material in the manufacturing of photo equipment, electroplating, and detergents.

According to statistics, 35.30% and 39.2% respectively of the daily consumption of glass in everyday-use, enamel, lightbulbs, and other light industrial industries in the 1990s was consumed by borax. At the close of 1980s, total glass and ceramics production reached 193,300 tons in terms of B2O3. By the dawn of the 21st-century, it had reached 71%.

8,97% of all soap was used to bleach and wash soap. 51,700 tons was spent on soap washing, while the bleaching use accounted for 1.3%. Cleansing and bleaching were also consumed at 1 million tons.

Since the dawn of the 21st century detergents, soaps and personal-care products accounted 15% of total global borate markets consumption.

Boride’s creep resistivity is high, which makes it an ideal material for rockets and gas turbines. Different alloys and/or cermets that contain borides (carbides) and nitrides can all be used to make rocket structural components, components for aircraft devices and high-temperature testing machines sample holders. These components also include bearings.

Calcium-boride properties:

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 C. and is very difficult to oxidize. CaB6 doesn’t dissolve in any hydrochloric or sulfuric acid. You can therefore remove impurities from hot hydrochloric. Material. CaB6, however, dissolves in nitric.

Calcium Hexaboride is granules or powder in the dark gray color. It has a melting temperature of 2230 ° C. The relative density is 2.33g/cm 2 and is insoluble when water is heated to 15 ° C.

Silicon boride is shiny, gray-colored powder that has a relative density (3.0g/cm) and a meltingpoint (2200 deg C). They are insoluble and resistant to water oxidation and heat shock.

Calcium boride main use:

1. Calcium boride, which is a boron-containing ingredient, can be added to dolomite, magnesium, orlomite, charcoal refractories in order to resist erosion, oxidation, and enhance 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), and amorphous borion.

6. As a raw materials for the production of high-purity borides, such as TiB2, ZrB2, TfB2, HfB2, etc. and high quality boron alloys (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-incrementer for boron alloy iron.

9. As a deoxygenator, desulfurization or boron increaser to boron steel.

Useful in deoxidizing metal smelting.
