Egypt is one of the best places which you can find the Highest and purist Quality Silica-sand, CairoMinerals offer Quality Products with Competitive Prices since 2004 but we are not only in the market, you can find many companies in Egypt as well deal with white silica-sand What is silica sand ? Silica (SiO2) sand is generally the sand which you can get all over a beach and it also happens to be the most commonly used sand. It is most commonly composed by either crushing sandstone or else it is most commonly taken from natural occurring points or locations, such as beaches and river beds. The fusion point of purest form of silica is 1,760 �°C (3,200 �°F), however the sands which is used for extraction of silica exhibits a lower melting point due to impurities. For casting which requires high melting point, such as steels, at least 98% pure should be used; however for metals having lower melting points, like cast iron and non-ferrous metals, the sand have low purity can be used (between 94 and 98% pure). Silica-sand happens to be the most commonly used sand because it is found in abundance, and thus it costs low (therein being its greatest advantage). However there are some disadvantages of sand as well. The disadvantages of silica are high thermal expansion, which can result in casting defects in metals having high melting point, and low thermal conductivity, which can very easily result in defective casting. Apart from there that, there comes some more barriers with it. It also cannot be used in sync with some of the basic metals because it will chemically react with the metal, resulting in surface defects. Finally, it releases silica particles during the pour, risking silicosis in foundry workers. Silica Sand for Sale Commercial Silica-Sand is most commonly used as a means of proppant by companies which deals in oil and natural gas recovery in conventional and unconventional resource plays. The resource is also utilized in industrial processing to manufacture regular use items such as glass, construction materials, personal care materials, electronics, and even renewable materials. Industrial sand happens to be a word which normally refers to silica-sand-products having extremely high purity with closely controlled sizing. It generally happens to be a clearer product than common concrete and asphalt gravels. The name Silica (SiO2) is provided to a handful of minerals solely made up of silicon and oxygen. Mostly it is found in the crystalline state. It is also found in an amorphous form which comes as a result of weathering or plankton fossilization Silica-sand deposits are generally mined and dig out in open pit processes. Extracted ore is subjected a lot of processing to enhance the silica content by reducing impurities. After that it is dried and sized to manufacture the best sized particle size distribution for the intended application.
