In order to develop tinted infiltration glass and its colorants, which can make the ceramic have good spectrum transmittance, color space, color stability and be suitable for clinical use, we selected the best prescription and confirm the ingredient and content of the colorants. Molten glass was prepared in Al2O3 crucible by heating the components to 1420 degrees C for 2 hours. The refractive index and thermal stability of the glass were investigated. The refractive index of the MIC infiltration glass was 1.5969(587.6 nm, nd). It was close to the index of aluminous matrix 1.759(546.07 nm, ne), which increased the spectrum transmittance of MIC. The thermal expansion coefficient of the glass was 7.565 microns/m/degree C, which was compatible with the thermal expansion coefficient of aluminous matrix(8.214 microns/m/degree C). This study proved that the tinted infiltration glass has good color stability, spectrum transmittance, and thermal expansion properties.
为了开发能使陶瓷具有良好光谱透过率、色彩空间、颜色稳定性且适用于临床的有色渗透玻璃及其着色剂，我们选择了最佳配方并确定了着色剂的成分和含量。通过在氧化铝坩埚中将各组分加热至1420摄氏度并保温2小时来制备熔制玻璃。研究了玻璃的折射率和热稳定性。MIC渗透玻璃在587.6纳米处的折射率（nd）为1.5969。它接近铝基质在546.07纳米处的折射率（ne）1.759，这提高了MIC的光谱透过率。玻璃的热膨胀系数为7.565微米/米/摄氏度，与铝基质的热膨胀系数（8.214微米/米/摄氏度）相匹配。本研究证明，有色渗透玻璃具有良好的颜色稳定性、光谱透过率和热膨胀性能。
