title: [Investigation of machinable-infiltrated-ceramic glass infiltrating through the aluminous matrix].
abstract: This investigation was amied at the infiltrative capability of the machinable-infiltrated-ceramic(MIC) glass and the color of the composite after the MIC glass infiltrated through the aluminous matrix with different packing densities. By heating the components to 1100 degrees C for 2 hours, the MIC glass was made to infiltrate through the aluminous matrix with different packing densities. We measured the infiltrative depth and the color parameter and observed the rupture surface of the composite by means of SEM. There was a linear relation between the square of infiltrative depth and the packing density of aluminous matrix. The minimal depth was 3.092 mm. No relationship was noted between the composite's color coefficient and the packing density of aluminous matrix. In the rupture process of the composite, crack deflexion, crystal evulsion, and rupture through crystal could be observed. This experiment proved that the infiltrative characters of MIC glass meet the clinical requirement, the composite's color is steady and the mechanical intensity is stable.
