Natural pearls are composed entirely of nacre, a combination of aragonite and an organic binder called conchiolin. In an effort to protect itself from an intruder, the oyster coats itself with layers of nacre, also known as mother-of-pearl, the same substance it uses for shell building.
zircon as a material for industrial ceramics, refractories (furnace or reactor lining materials that are resistant to high heat), to dyes. the use of zircon is developing in a number of industrial sectors, including: ceramic Industry, PSZ (Partially Stabilized Zirconia) glass industry, Zircon flour industry (micronized zircon), zirconium chemical industry, Refractory brick industry Printing sand industry. the use of micronized zircon or zircon powder in ceramic products accounts for almost half of the national consumption of this mineral. In the manufacture of ceramics, zircon flour serves as an opaque glaze for household items and ceramic tiles. Meanwhile, in the glass industry, zirconia (fused zircon) is used to produce glasses with special compositions, such as optical glass, fiber glass, color TV glass, and so on. In addition, the use of zircon is quite high in the metal industry. This mineral is used in the metal industry because it has heat-resistant properties. In practice, zircon flour is used to coat metal products, such as steel and bone iron, especially dry coating to produce kitchen and bathroom products. The use of zircon flour is also applied in the production of refractory bricks used to line steel or glass smelting furnaces. Zircon is also used in the nuclear sector. In this field, zircon is used as a cladding material for nuclear reactor fuel. As a coating material, zircon can withstand very high heat which is the result of fusion reactions in nuclear reactors.
