Characteristics of high-purity calcium carbonate:
1.High chemical purity and inertness: Heavy calcium carbonate boasts high chemical purity and significant inertness, making it unlikely to react chemically with other substances.
2.Excellent physical properties:
High whiteness: Typically, the whiteness ranges between 89% to 93%, with some products even exceeding 95%.
Low oil absorbency: Due to its large particle size, smooth surface, and small specific surface area, the oil absorbency is relatively low, typically around 40-60 mL/100g.
Low refractive index: Helps improve the transparency or appearance of certain materials.
Good thermal stability: Does not decompose below 400°C, maintains stability well.
Dry, non-toxic, tasteless, odorless: Ensures safe use in various applications.
3.Particle Characteristics:
Irregular particle shape: Significant variation in particle size, with some sharp edges and a rough surface.
Particle size distribution is wide: The average particle size is typically 1~10 μm, with larger particle sizes.
4. Good dispersion: Excellent dispersion in various media, facilitating even distribution in diverse applications.
5. Broad Applications: As a powdered inorganic filler, widely used in daily industries such as rubber, plastic, paint, and textiles, it can increase product volume, reduce costs, and improve product performance.
