Quartz A grade refer to high-quality quartz that are of the highest grade and purity. This grade typically has a SiO2 content of 99.9% and above, 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.

Natural Gypsum: Gypsum (CaSO4.2H2O) is a naturally occurring mineral mined from deposits formed by ancient sea beds as a raw material, white when pure, but commonly grey, yellow, red or brown, owing to impurities. The anhydrous form (CaSO4), anhydrite, is common. We are enlisted amongst the topmost INatural Gypsum Importers and Exporters from India. Applications: Gypsum has many industrial applications in its raw or Calcined forms, especially in the building and construction industries. Uses of Raw Gypsum are principally as: - a retarder for Portland cement - a fertilizer or soil conditioner - mineral filler - oxidizing agent in glass manufacture or other industrial applications. Most gypsum is calcined and used in the manufacturing of plaster products. Wallboard and plaster requires gypsum contents greater than 85%, although producers prefer a minimum of 94–95% along with whiteness in color. The major consumers of the Gypsum at present are Cement Industry. By weight about 4% to 6% Gypsum in crushed condition is utilized in Portland Cement Manufacture after mixing with cement/clinker. Gypsum acts as a retarder and controls the setting time of cement. Imported Gypsum from Iran: Natural Gypsum is one of the most superior qualities and consistent material available for Import and Export. Natural Gypsum has adequate whiteness, high purity as well as it is low in cost which makes it absolutely feasible for white cements as well as Plaster Of Paris manufacturing and for the Cement Industry all together. One more important quality that distinguishes Natural Gypsum from others is its hardness which is less as compared to other sources and allows different industries to easily grind the same for processing into final product which in turn results in to reduced power consumption for manufacturing industries.

Talc (Soapstone/Steatite) is a naturally occurring mineral primarily composed of magnesium, silicon, and oxygen and also referred to as Magnesium Silicate Powder. It is known for its softness, chemical inertness, and ability to absorb moisture, making it highly useful across various industrial applications. It is available in white powder with the particle size range of 40 to 10 microns.
We are supplier and exporter of Calcined Alumina. Calcined alumina can be used in the polishing of different alumina products(mainly used in middle, fine polishing).It is also widely used in high-class aluminium refractory material, unshaped refractory materials, high aluminium ceramic product and advanced coating, etc, . Item Al2o3 % Na2o % Sio2 % Fe2o3 % D50 A4m 99.8 0.1 0.05 0.02 3.1 Alumina (Al2O3), the industrial Al2O3 is prepared from alumina (Al2O3, 3H2O) and hard alumina, and the Al2O3, which is high in purity, is usually prepared by chemical methods. Al2O3 has many isomorphic crystals, and there are currently more than 10 known types, mainly three types of crystal, namely gamma-al2o3, beta-al2o3, alpha-al2o3.Which structure is different, with different properties in high temperature above 1300 s almost entirely into alpha Al2O3.
