Paper Title:
Effect of Sintering Systems and Colloidal Silica Sols on the Mechanical Properties of Oriented Silica-Based Ceramic Core Materials
  Abstract

A series of silica -based ceramic cores sintered at 1150°C, 1200°C for different times were prepared, and this study compared the three-point bending strength of room temperature and 900°C with commercially available colloidal silica sols systems. Three-point bend specimens 60 × 10 × 4 mm were cast by vacuum hot pressing and tested in a special mechanical testing machine with high temperature test system of ceramics. The effect of sintering systems and colloidal silica sols on the mechanical properties of ceramic core was discussed. It could be concluded that specimens sintered at 1150°C for 5h have an obtainable maximum bending strength and those immersed in colloidal silica sols contents showed doubled bending strength in the present research.
