Improvement on the Anti-Cracking Properties of Al2O3-SiC-C
The anti-cracking performance of A12O3-SiC-C based castables for trough was improved by the addition of foaming AC using silica ash or silica sol as binder. The differential thermal analysis and thermogravimetric investigations were carried out on different matrix slip to investigate cracking performance. The results revealed that the three ways were all effective in improving the anti

As a wear refractory commonly unburned Al2O3-SiC-C bricks are applied for the torpedo car. However the problem of decreasing torpedo car temperature and shell deformation exists because the thermal conductivity of graphite is high. We have developed a line of low thermal conductivity carbon containing refractories called "ECONOS" .
