1. The chemical composition of potassium calcium silicate mainly consists of silicon dioxide (SiO₂), calcium oxide (CaO),Diphosphorus pentoxideComposed of components such as (P₂O₅) and potassium oxide (K₂O), with the chemical formula KCaPSiO₆. The ratio can be adjusted according to requirements. For example, in polishing compound, this component constitutes 2.5-7.5% of the mixture, working synergistically with other ingredients (such as silicon dioxide, amino acid surfactants).

2. Structure and Properties: Calcium orthophosphate is typically a white or colorless powdered solid with high chemical stability and biocompatibility. Upon contact with water or saliva, it undergoes hydrolysis, releasing calcium ions,Phosphoric AcidRoot ions and potassium ions, among other active groups, are water-soluble amorphous active materials. Particle size ranges from micrometers to nanometers. Powders prepared by the sol-gel method have a larger specific surface area and higher reactivity. The porous surface structure enhances contact with saliva or body fluids, accelerating ion release and mineralization reactions.

Hydrolysis Reaction: Upon contact with liquid, this material undergoes a rapid series of hydrolysis reactions on its surface. Potassium ions (K⁺) and calcium ions (Ca²⁺) can quickly undergo ion exchange with H⁺ or H₃O⁺ in the water, while simultaneously hydrolyzing outPhosphoric AcidPhosphate ions (PO₄³⁻) and silicon hydroxyl ions (SiOH) until all the various ions in the liquid reach saturation.

Alkaline Environment: After hydrolysis, it forms an alkaline environment (pH 7-8), which can destroy the survival conditions of bacteria while avoiding irritation to the oral mucosa.
