21. Then there's the thermal expansion and contraction cycles a varying temperature will cause. 22. Up to about 300 �C, the concrete undergoes normal thermal expansion . 23. Additionally, the sheet metal retaining the insulation requires some provision for thermal expansion . 24. Iznik pottery was produced in thermal expansion coefficient of the ceramic. 25. For example, the coefficient of thermal expansion increases by several hundred percent upon melting. 26. Apart from thermal expansion , generation through the deformation potential or through piezoelectricity is possible. 27. Their very low coefficient of thermal expansion makes them less prone to thermal shock. 28. Thermal expansion led to volcanic activity, which broke the land mass into smaller continents.29. This is because the brittleness of glass does not allow for uneven thermal expansion . 30. Differing coefficients of thermal expansion pose challenges for anodic bonding.
