Talcum Powder Paper-Making Grade 800mesh Fine Powder for Papermaking
Product Description
Our premium talcum powder is a naturally occurring, ultra-fine white mineral powder with distinctive physical characteristics. The powder exhibits an exceptionally smooth texture with a characteristic greasy feel, while remaining completely odorless and tasteless. This high-purity product contains no sand or gritty particles, ensuring superior quality for sensitive applications.
Chemical Composition
The primary constituent is hydrous magnesium silicate (Mg₃Si₄O₁₀(OH)₂), with a typical chemical composition of:
Magnesium oxide (MgO): 31-33%
Silicon dioxide (SiO₂): 60-63%
Bound water: 4-6%
Manufacturing Process
The production of our high-grade talcum powder involves a rigorous purification protocol:
Primary crushing of raw talc ore to reduce particle size
Hydrochloric acid treatment (5-8% concentration) to dissolve carbonate impurities
Intensive water washing with deionized water
Neutralization and pH adjustment
Precision drying using controlled-temperature systems
Ultrafine milling to achieve optimal particle size distribution
Final quality verification through advanced analytical methods
