Virtual International manufactures and supplies high-purity Dolomite Powder, a double carbonate mineral containing both calcium and magnesium. We carefully crush, grind, and classify select dolomite rock to produce a fine, consistent powder with excellent whiteness and chemical stability. This versatile mineral functions as a cost-effective filler, a powerful pH buffer, a fluxing agent, and a source of essential minerals. Industries from steel and agriculture to glass and plastics rely on our Dolomite Powder to enhance product performance, optimize processes, and improve cost-efficiency.

Key Features & Benefits

• High Purity & Whiteness: Our dolomite features high levels of CaMg(CO3)2CaMg(CO3?)2? and low impurity content, providing excellent brightness for filler applications.
• Dual Nutrient Source: In agriculture, it delivers essential calcium and magnesium to the soil, correcting deficiencies and improving plant health.
• Effective pH Neutralization: Its alkaline nature makes it highly effective for neutralizing acidity in soils, water, and industrial processes.
• Excellent Filler Properties: With its high hardness and density, it improves scratch resistance, durability, and bulk in paints, plastics, and rubber compounds.
• Consistent Particle Size: We offer various grades with controlled particle sizes (mesh/microns) to meet the precise requirements of your application.

Major Industrial Applications

Agriculture:

• Farmers and agronomists apply Dolomite Powder (dolomitic lime) to agricultural soils to correct acidity (raise pH) and supply essential magnesium and calcium.

Steel Manufacturing:

• Steel producers use dolomite as a fluxing agent in blast furnaces and converters to protect furnace linings and remove impurities like sulfur and phosphorus from molten steel.

Glass & Ceramics:

• Glass manufacturers add it to the melt to improve the durability and weather resistance of flat glass.
• In ceramics, it acts as a flux and a source of magnesia.

Paints, Plastics & Rubber:

• Formulators use it as a functional filler to increase volume, enhance weatherability, and reduce formulation costs in a variety of polymer systems.
