1. Chemical composition: the main ingredients determine the quality and characteristics of silica brick.
2. The bulk density: per unit volume weight, density is large, indicating the density is good, the strength may be high, but the thermal conductivity may be large.
3. The porosity: no specific requirements, but as a manufacturer must strictly control the porosity.
4. Load softening temperature: also known as high temperature load starting deformation temperature, this parameter is very important, marking the material the ability for resistance to high temperature.
5. Thermal shock resistance: ability to resist rapid temperature change and is not damaged.
6. Compressive strength: to withstand (room temperature) the maximum pressure capacity
7. Bending strength: the ability to withstand shear pressure
8. The linear rate of change: also called the re-burning line changes or called the residual line changes, that each time the volume of expansion and contraction change in the same temperature, if each expansion contraction is same, we define such a linear rate of change is zero.
Physical and chemical properties
1. Wear resistance.
2. Thermal conductivity: under the unit temperature gradient conditions, Through the material of heat flow rate per unit area, related the porosity.
