The CTE of the composite was shown to be dependent on the volume fraction of the broken particle, plastic yielding and flow, and other transformation processes occurring at elevated temperatures. The experimentally measured values of the CTE were found to be in good agreement with Schapery's ...

(CTE) and Young’s modulus between Al2O3ceramic and other materials, the joining of Al2O3ceramic and other materials is difficult. The most commonly used method for joining Al2O3ceramic and other materials is brazing. Besides, transient liquid phase (TLP) bonding is also an approp...

Hv, E and CTE properties are related to the crystalline phases formed during the crystallization treatment, and their variations are in accordance with the increase of the crystal aspect ratio. The CTE values of the GCs decrease as the P2O5 content increases up to 3%, while for the Al2O3 ...
likely due to insufficient liquid phase flow and higher viscosity of the residual glass phase. These observations highlighted the importance of glass composition in achieving desirable densification and microstructural characteristics. They also measured the coefficient of thermal expansion...
3) Small Coefficient of Thermal Expansion (CTE) Covalent bond compounds generally have high melting point, and the higher the melting point, the smaller the thermal expansion coefficient, so the CTE of ceramic materials is generally small. 4) High Thermal Conduc...
