Product type
Limestone powder is a finely ground form of limestone, primarily composed of calcium carbonate. It is produced by crushing and grinding limestone rock to a fine powder. This versatile industrial mineral is commonly used in various applications due to its chemical properties and availability. It serves as a filler, a flux in steel production, and a key ingredient in the manufacture of cement and glass.
| Chemical composition | Primarily calcium carbonate (CaCO3) |
| Particle size | Typically ranges from 5 to 100 microns |
| Purity | Usually between 90% to 98% calcium carbonate |
| Moisture content | Generally less than 1% moisture |
| Bulk density | Approximately 0.8 to 1.2 g/cm³ |
When selecting limestone powder, buyers should consider the desired purity level and particle size based on their specific application. It is also important to specify any required certifications or standards, particularly for food-grade or pharmaceutical uses. Quantities can vary significantly based on the scale of the project, so providing an estimated volume will help suppliers provide accurate quotes.
