Whiteness: Achieves a whiteness of 93% ± 2%, high whiteness reduces interference with the luminescent powder's performance as a carrier, ensuring light purity and brightness; improves the transparency and visual effect of glass in optical glass manufacturing. Density: Density ranges between 3.0-3.8 g/cm³, this density range provides good physical stability to the product. In specialized functional material applications, appropriate density aids in maintaining structural integrity during shaping, e.g., in the preparation of radiation shielding materials, it ensures effective blocking of radiation. Moisture Content: Moisture content is strictly controlled to ≤0.1%, the extremely low moisture content effectively prevents bubble formation and affects material density during high-temperature sintering, ensuring product quality stability and reliability. Softening Point: Softening point is adjustable within the range of 300-500°C, allowing the product to flexibly adapt to various processing techniques and application scenarios. A lower softening point is suitable for low-temperature shaping processes, such as LTCC (Low Temperature Co-Fired Ceramic) substrate manufacturing, which reduces energy consumption; a higher softening point is suitable for high-temperature resistance applications, such as the preparation of high-temperature sealants. Coefficient of Thermal Expansion: The coefficient of thermal expansion is 5.0-9.0×10⁻⁶/°C, this parameter determines the product's dimensional stability under temperature change conditions. When used in combination with other materials, a similar coefficient of thermal expansion effectively reduces cracks and deformation caused by thermal stress, ensuring the overall performance of the material system, particularly crucial in optical and electronic applications.
