What are the main properties of silicon brick and clay brick What are their strengths and weaknesses
Load softening point: the load softening point of silicon brick is relatively high, and its value is related to the chemical composition of silicon brick.
Thermal expansion: silicon brick is different from other refractory materials, the expansion is very intense before 600 ° C, and reaches its peak at 600 ° C. The expansion of the ghost pack is little after 1000℃, after full sintering, the quartz is transformed into squame-quartz and cristobalite, the higher the degree of sintering, the smaller the residual expansion of the silicon brick.
