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
