Dolomite powder is used as a raw material for the production of high-grade glassware, medicine bottles and optical glass.
Dolomite powder has limited dosage in paints, confined to be used as filler, mainly playing the role of white pigment. However, due to the coarse particles, refractive index and paint solvent similar to the covering power is weak, there is no certain special role in the application, just for the body pigment filler paint.- Used in the building materials and refractory materials, chemical and agricultural, environmental protection, energy conservation and other fields.
- Used in the production of glass and ceramic ingredients;
- Used as refractory inner layer, slag making agent, cement raw material, glass flux, kiln industry, building and decoration stone material, paint;
Calcium carbonate powder is derived from the mineral calcium carbonate, which is naturally found in rocks and shells. It is a white, odorless powder that is highly versatile and widely used in various industries. In the context of health and wellness, calcium carbonate powder is a popular dietary supplement due to its high calcium content.
Ground calcium carbonate powder is widely recognized for its various advantages. It is known to enhance the strength and durability of materials, making it a popular choice in construction and manufacturing industries. Additionally, it can act as a filler, improving the performance of products like paint, rubber, and plastics. It also offers environmental benefits by reducing the carbon footprint in certain applications.
With a range of uses, ground calcium carbonate powder finds its way into everyday products. From toothpaste to medications, from paper to cosmetics, its versatility is undeniable.
1. Product Overview
Ground Calcium Carbonate (GCC) is a naturally occurring mineral obtained from high-purity
limestone or marble. It is mechanically ground into fine powder without changing its chemical
structure. GCC is widely used in various industrial applications due to its excellent physical and
chemical properties.

Silica sand, also known as quartz sand, is composed mainly of silicon dioxide (SiO). It is a naturally occurring mineral that is commonly used in a variety of industries due to its properties like durability, high melting point with low iron content , customization and resistance to weathering. Here are some common uses and facts about silica sand:
Common Uses:
Glass Manufacturing: Silica sand is a primary raw material in the production of glass, including container glass, flat glass, and specialty glass.
Construction: It is used in concrete, mortar, and other construction materials, as well as for sandblasting.
Foundries: Silica sand is used in foundry molds and cores for casting metal parts.
Water Filtration: The sand is used in water filtration systems because of its ability to trap contaminants.
Oil & Gas Industry: It is used in hydraulic fracturing (fracking) to prop open fractures in shale rock to extract oil and natural gas.
Sports & Leisure: Silica sand is used in products like sandboxes, golf course bunkers, and artificial turf.
Properties:
Hardness: Silica sand is known for its hardness, typically ranking around 7 on the Mohs scale, which makes it useful for many industrial applications.
Grain Size: The grain size of silica sand varies, with smaller grains being used for things like glass and larger grains being used for sandblasting or filtration.
Color: It can vary in color, from white to tan or even pink, depending on impurities and iron content.
