Generally, we offer...Diphosphorus pentoxide(P2O5) serves as the primary glass-forming component, and may also contain alkali metal oxides (such as Na2O, K2O), alkaline earth metal oxides (such as CaO, MgO), and other metal oxides (such as Al2O3, ZnO, etc.). The varying proportions of these components lead toPhosphoric AcidSalt glass powder varies in performance.
Acidity: Due toPhosphoric AcidThe presence of salt carries a certain acidity.
Solubility: Generally, insoluble in water and most organic solvents; soluble in acidic solutions.Phosphoric AcidThe dissolution rate of salt glass powder typically accelerates as acid reacts with basic oxides in glass, disrupting its network structure. In an alkaline solution, its solubility is relatively lower.
Appearance: Typically a white or colorless transparent powder, particle size can be controlled according to different production processes and requirements, usually in the micron range or finer.
Density: The density is relatively high, typically around 2.5-3.0 g/cm³, due to the closely packed atomic arrangement and the relatively high atomic masses of elements like phosphorus and silicon.
Hardness: Possesses high hardness, with a Mohs hardness typically ranging from 5 to 7, suitable for applications requiring good wear resistance.
Good thermal stability: Maintains stable physical and chemical properties within a certain temperature range, can withstand high temperatures without significant deformation or melting.
Coefficient of Thermal Expansion: The coefficient of thermal expansion is relatively small and adjustable, typically around (5-10)×10⁻⁶/°C. This allows it to match well with many materials in terms of thermal expansion, making it suitable for applications requiring sealing or bonding with other materials.
Optical Performance
Refractive Index: The refractive index typically ranges from 1.5 to 1.7, adjustable according to specific composition, which allows it to have certain applications in the optical field, such as manufacturing optical lenses, prisms, and other optical components.
Transparency: Offers excellent transparency in the visible light and near-infrared spectrum, with a transmission rate exceeding 90%. Suitable for components or materials requiring light transmission.
Insulation: Possesses excellent electrical insulation properties with high resistivity, typically ranging from 10¹² to 10¹⁵ Ω・cm, suitable for electrical insulation materials and other applications.
Application Fields
Electronic Packaging: With its excellent insulating and sealing properties, as well as matching thermal expansion coefficient to electronic components, it has become an ideal material in the electronic packaging field. Suitable for manufacturing insulating coatings for electronic components, packaging shells, and substrate materials.
