Silica mullite brick is a kind of common refractory material, mainly used in high temperature equipment lining. In the use of silicon Mo brick, we generally need to understand its physical and chemical indicators, the following is to introduce the physical and chemical indicators of silicon Mo brick.
1, chemical composition: the main components of Silica mullite brick is silicon dioxide and mullite, which silica in 65%~70%, mullite between 30%~35%.
2, normal temperature compressive strength: the normal temperature compressive strength of silicon brick is usually more than 80 MPa.
3, linear expansion coefficient: silicon Mo brick linear expansion coefficient is small, usually in (0.5~1.5) × 10^-6/℃.
4, refractoriness: the refractoriness of silicon Mo brick is high, usually between 1750℃~1800℃.
5, density: the density of silicon Mo brick is relatively large, usually between 2.5~ 2.7g /cm³.
6. Thermal conductivity: The thermal conductivity of silicon brick is small, usually between (0.8~1.0) W/(m·K).
7, seismic performance: silicon Mo brick has good seismic performance, in the vibration environment can still maintain stable physical and chemical properties.
It should be noted that the physical and chemical indicators of silicon Mo brick produced by different manufacturers are different, and the appropriate products should be selected according to the actual demand. At the same time, when using silicon Mo brick, it is also necessary to pay attention to its installation and maintenance methods to ensure its normal service life and performance.
