Dolomite Sand
Overview
Dolomite Sand is a naturally occurring mineral composed of calcium magnesium carbonate. It is derived from dolomite rock, which is crushed and processed into various grain sizes for different industrial applications. The material is known for its high magnesium content, which makes it valuable in agriculture and construction. Dolomite Sand is widely used due to its versatility and cost-effectiveness. It is available in multiple specifications, catering to diverse industrial needs. The material is also environmentally friendly, making it a preferred choice for sustainable projects.
Physical and Chemical Properties
Dolomite Sand exhibits a white to gray appearance and is available in granular or powdered forms. It has a high density and is insoluble in water, though it dissolves in acidic solutions. The material is thermally stable, decomposing at temperatures around 1,300°C. Chemically, Dolomite Sand is alkaline, which makes it useful for neutralizing acidic soils and water. Its high magnesium content (up to 21%) is particularly beneficial for agricultural applications, where it serves as a soil conditioner and magnesium supplement.
Main Applications
In construction, Dolomite Sand is used as an aggregate in concrete and asphalt, providing durability and strength. It is also employed in the production of refractory materials due to its high thermal stability. In agriculture, the material is used to neutralize acidic soils and supply essential magnesium and calcium nutrients. Additionally, Dolomite Sand finds applications in glass manufacturing, water treatment, and as a filler in paints and plastics.
Safety and Storage
While Dolomite Sand is non-toxic, prolonged inhalation of dust particles may cause respiratory irritation. It is advisable to use protective gear such as masks and gloves when handling the material. Storage should be in a dry, cool environment to prevent moisture absorption and clumping. Avoid contact with acids, as the material reacts vigorously, releasing carbon dioxide.
B2B Procurement Guide
When procuring Dolomite Sand, consider factors such as purity, grain size, and moisture content. These parameters determine the material's suitability for specific applications. Suppliers should provide certificates of analysis to verify quality. Prices vary based on specifications and quantity. Bulk purchases typically offer cost savings. Ensure reliable logistics for transportation, as the material is heavy and may require specialized handling.
