Paper Title:
Influence of Heat Treatment Temperatures on Properties of Unburned Al2O3-C Slide Plate
  Abstract

Unburned Al2O3 - C slide plate specimens were prepared at different temperatures, using tabular corundum, graphite, Al, Si powder as starting materials and silicone resin as binder. The results reveal that heat treatment temperatures have a significant impact on the performance of unburned Al2O3 - C slide plate. Between 200°C and 600 °C, the internal structure of the specimens is loose, and the apparent porosity increases significantly, meanwhile the cold crushing strength is very low. Between 800 oC and 1000 °C, the bulk density increases significantly, the apparent porosity have a sharp decline, and the cold crushing strength value increases. Over 1000 °C, there are many holes in the specimens, specimen mass and thermal expansion significantly increases, the bulk density decreases, and the apparent porosity increases, in the same time, the cold crushing strength has a downward trend.
