What is Quartz Sand?
Quartz sand is quartz (SiO2) particles smaller than 2 mm formed as a result of the weathering of magmatic, metamorphic rocks rich in quartz. Quartz is a chemical compound made up of one part silicon and two parts oxygen. It is silicon dioxide (SiO 2). Its unique properties make it one of the most useful natural ingredients. Quartz sand has the highest purity in nature, quartz, which is one of the hardest and most durable mines in the world, is extracted from our mines with very special systems and subjected to crushing and screening processes in our factory for processing. It is carefully prepared for our customers in crushing and screening machines brought from Europe and extracted from pure white and 99% purity. The most precious jewels of our country contribute to the economy of our country by carefully controlling the distribution of sieves at the highest levels by engineers in our laboratories.
Where is it?
Occurs at any temperature. It is abundant in igneous, metamorphic and sedimentary rocks. It is highly resistant to both mechanical and chemical weather conditions. This endurance makes it the predominant mineral of mountain peaks and the primary component of beach, river, and desert sand.
The main areas of use of quartz sands are glass and casting industries, and they are also used in the construction industry, the production of abrasives, metallurgy, detergent, paint plastic, rubber, ceramic industries and oil production.
It is prepared to be a product in a wide variety of usage areas. After the crushing process is done very carefully during the production phase, it is separated in 10 steps starting from 0 micron up to 2-3 mm with a special sieve system. Our company continues its R&D activities in this regard without slowing down and continues its investments to increase its production capacity day by day.
The high hardness of quartz, which is seven on the Mohs Scale, makes it harder than many other natural materials. Therefore, it is an excellent abrasive material. Quartz sands and finely ground silica sand are used in the production of sandblasting, scouring cleaners, grinding media and abrasives for sanding and sawing.
In floor coverings, construction chemicals, kitchen countertops in the chemical sector are also very widely processed and appear as a very stylish design. The fact that it is a very hard metal is used not only in our industry but also as a visual, and has a very distinguished structure for insulation purposes in therapy centers. Quartz sand extracted in very rare regions in our country is classified under very difficult conditions and is subjected to crushing.
Both our crushed and natural quartz contribute to the economy and have an important place in exports. The fact that it is rarely seen in certain places in the world increases the importance of pure white or yellowish quartz that we produce in our country. Our company has built the world's most modern crushing and grinding and washing facilities with 20 years of experience in becoming indispensable for our industry, and with all the necessary R & D studies, all kinds of micron 0-100 mm 0-200 mm and 1.mm 2mm serve the electrical industry. has reached the top in production quality.
Quartz, which is available as powder, continues to be indispensable in the field of electrical energy. Most of the quartz crystals used in electronic components and optical instruments today are grown in laboratories rather than mines. Most laboratories grow their crystals using methods based on the geological process of hydrothermal activity. Synthetic crystals are grown at high temperatures from superheated waters rich in dissolved silica. These produced crystals can be grown in shapes, sizes and colors that suit the needs of the production processes. Quartz sand is also used on beaches, baseball fields, golf courses, volleyball courts, as well as children's sandboxes, and is also used for traction on railways and mines.
The sand color of the quartz mineral is white, and the color of sands containing iron oxide can range from pink to red or brown. Quartz sand is one of the hardest minerals due to its high hardness (7Mohs). Quartz is one of the most useful natural materials. Its usefulness can be attributed to its physical and chemical properties. Since it has a hardness of seven according to the Mohs Scale, it is very durable. It is chemically inert in contact with most substances. It has electrical properties and heat resistance that make it valuable in electronic products. Silica sand (quartz) is generally in yellow, gray, beige and white colors. The difference between silica sand and quartz sand is curious. There is no difference between natural quartz sand and silica sand, except for non-crushed quartz sand. Silica quartz sand is the main ingredient in glass, allowing chemicals to shine under the sun. Silica sand and pebbles (quartz) are known for their versatile uses. Silica sand and pebbles have high abrasion, extreme weather resistance and high chemical stability.
Quartz Sand Standards:
The quartz sand used in casting should be -0.7 mm +0.1 mm in size and have a balanced distribution in this size range, and should not sinter below 1500 ° C. In this area, the sand should contain a minimum of 95 -96% SiO2, and the sum of Fe2O3, CaO and alkali should not exceed 0.6%.
Quartz sand, which will constitute the raw material in glass production, must contain a minimum of 98% SiO2, a maximum of 0.1% Fe2O3 and a grain size range of -0.5 +0.106 mm.
