Core Physicochemical Properties
1.Excellent Biocompatibility: Its composition is consistent with human bone tissue, making it non-toxic, non-irritating, and free from immune rejection.
2.Osteoconductivity: Capable of guiding new bone growth to achieve bone tissue repair and integration.
3.High Adsorption Capacity: Possesses strong adsorption capabilities for heavy metal ions, fluoride ions, proteins, and bacteria.
4.Thermal Resistance & Chemical Stability: Heat resistant and stable against acids and alkalis, making it difficult to decompose.
5.Tunable Porous Structure: Can be fabricated into porous materials with high specific surface area, suitable for adsorption and carrier applications.
Application
1. Oral Care (Mainstream Consumer Use)
Additives: Used as an additive in toothpaste and mouthwash.
Benefits: Repairs enamel, desensitizes, prevents cavities, whitens teeth, and reduces plaque.
Target Audience: Serves as a fluoride substitute, suitable for children and individuals with sensitive teeth.
2. Biomedical Materials
