Quartz or quartz of pure silica consists of impurities (silicon dioxide SiO2). Quartz and pure transparent colorless and is one of the most hardness of metals and minerals that few superiority in hardness diamonds, rubies, topaz and beryl and Alosnpil. When exposing the quartz crystal to power it generates an electric compressor on the edges and vice versa effort to shed When a voltage alternating them, they vibrate a specific and precise frequency. The advantage of this phenomenon, known Balbizokahrbaiah (piezoelectricity) in the manufacture of fine quartz hours and Mahtzac in electronic devices. With the exception of aluminum silicate is more of quartz materials used in the composition of the rocks in the earth's crust has been the degree of hardness of seven degrees.
