![]() ![]() It also helps to make glassware for science labs. It produces high end cookware materials used in brands such as Duran and Pyrex. ![]() Borax is a powdered material used in detergents, cosmetics, and enamel glazes.īoron is used in the manufacture of glass and ceramics. Boric acid is used in a number of applications including insecticides, flame retardants, antiseptics, and to create other compounds. Most of the boron that is mined is eventually refined into boric acid or borax. The most common compounds are borax and kernite which are found in sedimentary rock formations. Pure boron is not found naturally on Earth, but the element is found in many compounds. It is a poor conductor at room temperature.īoron is a fairly rare element on Earth. The chemical compound boron nitride is the second hardest substance after diamond (which is an allotrope of carbon).īoron tends to make covalent bonds rather than ionic bonds. Crystalline boron is black in color and is extremely hard. The boron atom has five electrons and five protons.Īmorphous boron (meaning the atoms are bonded together in a random order) comes in the form of a brown powder.īoron atoms can bond in a number of different types of crystal networks called allotropes. It is classified as a metalloid which means that its properties are in between that of a metal and a nonmetal. Thenard, and Sir Humphry Davy in 1808īoron is the first element in the thirteenth column of the periodic table. ![]()
