Quartz is one of the most actively found minerals on the earth. It is also one of the most used minerals, it can be found easily in our day to day lives. High-quality quartz is used in numerous industries including semiconductor, solar, optical, and lighting industries. Properties of quartz are essential in manufacturing some very high tech products, that also includes mobile phone we use day to day. Quartz is also highly used in the manufacturing of ceramic products.
Hariom Minechem has recently expanded its operations in the field of high purity quartz and acquired three mining leases in the rich belt of Rajasthan. The company plans to diversify its quartz portfolio and venture into high purity quartz business.
We are manufacturing and processing quartz lumps in different grades as per industry requirement. We are manufacturing quartz lumps and grit. We are also manufacturing quartz grits from 20mm to 150mm.
Our silica powder has following specifications:
High content of SiO2 from 99.5% to 99.9%
low content of alkali, or traces
Low Fe content upto 0.01%
Mohs hardness:7-7.8
Specific Gravity: 2.90-2.8
We (sri venkateswara minerals) are having our own mines of quartz and quartzite located in andhra pradesh, india. Our organization is widely reputed in offering quartzite lump to our clients as they required.
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content.
*physical properties of quartzite: hardness= 6.5- 7.2 on mho's scale.
Density = 2.3 to 2.4 kg/cm3.
Porosity = low to very low.
Weather impact = resistant.
*chemical properties of quartzite: sio2 = 97.5 - 98.5%
Fe2o3 = 0.5%-1.5%
Al2o3 = 1 to 1.5%
Na2o & kro = less then 1%
Cao = Less then 0.5%
Mgo = less then 0.5%
Loi = less then 0.5%
*uses of quartzite:
Quartzite is mainlly used in ferro alloys industries for producing ferro silicon(fesi) and silicon manganese(si mn) and also used in ceramic, glass industries. Because of its hardness and high resistance it is also used as refractory material.
We provide quartzite in different sizes (0-5mm, 10-40mm, 40-60mm, 60-100mm).
And quartzite powder 100 mesh and above.
White Quartz Powder: Quartz Powder is also used as an abrasive material and in processes like stonecutting, sandblasting, glass grinding etc. Quartz is also used in the lighting industry, laboratory, solar, telecommunications, semiconductor engineering, investment casting etc.
Quartz chips of M grade are similar to quartz lumps of M grade in terms of their high purity and particle size. They also have a minimum SiO2 content of 99.95% and are considered to be of medium grade, with a particle size ranging from 1mm to 6mm. Quartz chips are commonly used in the manufacturing of high-quality glass, ceramics, and electronics components. They are also used in the construction industry as an additive to concrete and mortar to increase strength and durability. The M grade quartz chips are preferred in applications where a medium particle size is required. They are often used as a filler material in the production of refractory products, such as high-temperature insulation and linings
Quartz A grade refer to high-quality quartz that are of the highest grade and purity. This grade typically has a minimum SiO2 content of 99.60 - 99.99%, making them suitable for use in industries where high purity is critical, such as in the production of high-quality optical lenses, semiconductors, and other electronics components. Quartz A grade has a particle size ranging from 1mm to 10mm, in the case of Lumps, depending on the specific application. They are carefully selected and processed to ensure that they meet strict quality standards, including low levels of impurities and uniform particle size distribution.
