Interpretation:
The typical values for the percentage of linear thermal expansion of refractories should be determined. Also, the comparison of plot for zirconia and alumina linear thermal expansion at a given reference temperature should be done.
Concept Introduction:
Linear expansion is defined as the increase in the length of a material in context with increase in the temperature of the material. Formula used for calculating the linear expansion is given below:
Where,
Thermal expansion is the tendency of the material to change its shape, area, and volume corresponding change in temperature.
Refractories are defined as the nonmetallic material which withstand high temperature based on the chemical and physical properties. Refractories are of following types:
- Acidic refractory
- Basic refractory
- Neutral refractory
