What are the main properties of silicon brick and clay brick? What are their strengths and weaknesses?

The main properties of silicon bricks are true density: true density is a very important indicator to measure the quality of silicon bricks, and even the true density can be directly used to explain the properties of silicon bricks. According to the reduction of true density, the degree of sintering of silicon brick and whether abnormal expansion occurs in use can be undetermined.

$Silicon brick is different from other refractories, the expansion is very intense before 600 ° C, and reaches its peak at 600 ° C. The expansion of the ghost pack is little after 1000℃, after full sintering, the quartz is transformed into squame-quartz and cristobalite, the higher the degree of sintering, the smaller the residual expansion of the silicon brick.$

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.
