Brick Clay — Thermal Expansion
Brick and tile products contribute significantly to the development and quality of construction projects all over the world.
This figure of a brick clay measurement exhibits a step in the thermal expansion curve (red) at 576°C which can clearly be seen in the physical α-curve as a peak at 587°C. This change in thermal expansion isd ue to the overlapping dehydration of clays and Phase TransitionsThe term phase transition (or phase change) is most commonly used to describe transitions between the solid, liquid and gaseous states.phase transition of quartz. Above 800°C, SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. sintering starts. During the sintering process, a melting effect can be observed which could be due to an inorganic component of the raw material.
