| Mountains contain contains a lot of secret and treasures, there are inside, precious and rarest metals in addition to guaranty the stability of of Earth working to maintain balance on the surface of Earth in addition to the embedded resources, there may be countries wish it economy is based actually on this wealth and all sources of income are of minerals within these mountains, but most people don't know that there are many of minerals within these mountains, we do not know anything about it or do not know they exist in the mountains. So let's Take a look at some of these metals and there most important of all: Silica Sand: The silicon oxide or white sand or sand glass, the chemical formula: SiO2 This sand exist in nature in quartz is a pure white sandy rocks contain a high proportion of silica and then crushed so that it take the form of grains of sand. This Sand known Since ancient times it is not a new thing ,it was known to the ancients they used it in the manufacture of glasses also was used in the manufacture of foundry, the term of glass sand is also called on the sands of silica or white sand. high-quality glass is made from silica and silica gel used for keeping the material from humidity is also used in water purification as well as in paints and also in the materials used in the manufacture of concrete in order to add her strength and durability and is also the most abundant metal of minerals in the earth's crust the metal enter in many industries, such as: Glassware, crystal glass, plate glass, fiber glass, optical glass, templates plumbing materials, refining and pottery, bricks, filters water purification plants, waste water, swimming pools, and as a filler and extensor in the manufacture of rubber, plastic, paper, paints and in a special type of cement in various chemical industries, as well as a factor to a reduced degree of leaching of oxides in the basal melting operations. The silica sand extraction process is easy and inexpensive the price of silica sand as a material is cheap, easy access and retrieval, but the transfer of classified and expensive, being a very solid and fused at high temperature Silica gel: Is a silica material, but in the form of mutant or different from, the basic form is a granular crystalline transparent and have no odor and no color is also transparent in nature Have a very important property which is the ability high and high to absorb the moisture, that is why we find the bags and packages of silica gel used in the things that damage from humidity, we find silica gel in the food to save them from moisture and odors and are also found in the tools and electrical appliances and also electronic devices as well as materials and leather works Also used in the separation of natural compounds because silica Featuring with a high polarity, so we passed the material we want to separate in columns of silica and this Facilitate the process of separating each product separately Also used in electrical transformers to save the humidity inside to work Successfully. Silica is inherently harmless substance and has no color is transparent and does not have any smell, but caution must be addressed and should not touch the children always find written on it (not for food) Advantages of silica gel High mechanical strength higher absorption of heat and humidity High chemical stability Thermal stability is very new |
