Boron is an essential chemical element for plants and an important one for animals (but in small doses). The name of the chemical element has Arabic roots, and in its pure form boron is dark color powder. However, it does not exist free in nature, only as a part of chemical compounds, with borax being the most popular of those. Boric acid is extensively used in medicine as an antiseptic, and boric oxide is often used to increase the strength of glass. Boron is a metalloid, so it demonstrates properties of both metals and non-metals.
Use of Boron
Boron (B), is generally used in chemical compounds. And it is extensively used in fiberglass. Boron is very important for domestic and international glass industry.
Boron compounds are also preferred in metallurgy, in industrial processes, in polymers, in the wood protection too. Boron makes products to be more resistant to physical impacts in ceramics. About 13% of boron consumption in the world is used for the ceramic industry. Today boron is also important in the agricultural industry. It increases agricultural yields and plays an important role in improving sustainability in agriculture.
Because it is very effective, boron is also used in detergent industries and industrial cleaners. Boron insulation materials are water resistant, long lasting, affordable, dust and heat free. So they provide heat, noise and fire insulation in living spaces.
