粉浆涂塑铝瓷核冠强度的提高有赖于玻璃料对铝瓷底层的渗透。本研究通过比较７件ＧＩ－Ｉ型粉浆涂塑铝瓷底层渗透前后的重量变化，测试出渗透铝瓷底层所需玻璃料的重量。结果显示，ＧＩ－Ｉ型粉浆涂塑铝瓷底层完全渗透所需玻璃料的重量为其自身重的３７．８％ The strength of plaster-coated aluminum-ceramic core depends on the penetration of glass frit into the underlying aluminum. In this study, the weight of the glass frit required to penetrate the aluminum substrate was tested by comparing the weight change before and after infiltration of the seven GI-I coated aluminum-plastic coated aluminum substrates. The results showed that the weight of the glass frit required for complete penetration of GI-I coated aluminum-plastic coated aluminum bottom was 37.8%
