Binding agent Si ratio increases, the refractoriness will rise

The results show that compared to the binding agent Si performance impact is more prominent. Si ratio of 0.35, the refractoriness of 870 ℃, the flexural strength reached a maximum 74.41MPa. In Clay - feldspar - borosilicate glass-based binders, maintaining unchanged the content of  cutting tools , with the binding agent in Al-Si ratio increases, the refractoriness will rise, further reduced mobility  grinding wheel  first small. The flexural strength  Diamond blade , and the peak sintering temperature as the aluminum-silicon ratio direction. Add the refractoriness silica decreased, while no apparent regularity strength.
