Research PaperPreparation and encapsulation performance of Al2O3-SiO2-B2O3 glass-ceramic for high temperature thermal storage
چکیده انگلیسی


- Al2O3-B2O3-SiO2 has good chemical durability, corrosion resistance and dense structure.
- The material rarely used in high temperature thermal storage.
- The material was prepared and characterized in the paper.

In this paper, Al2O3-SiO2-B2O3 glass-ceramic was prepared and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), further, the porosity was detected by Archimedes principle, thermo physical properties were investigated by differential scanning calorimeter (DSC), respectively. The phase composition was detected by XRD, and the morphology was observed by SEM. The results indicated that the thermal conductivities of the Al2O3-SiO2-B2O3 glass-ceramic were between 1.3 and 1.5 W·(m·K)−1, and the material had good thermal stability in the range of 300-900 °C. The porosity and apparent density were increased with the temperature. The porosity of Al2O3-SiO2-B2O3 glass-ceramic in ranging from 1.2 to 9.6%, the apparent density were between 2.12 and 2.67 g·cm−3, and heat capacities were between 0.64 and 0.79 kJ/(kg·K). All the results indicated that the Al2O3-SiO2-B2O3 glass-ceramic can be applied as encapsulation material in high temperature latent thermal energy storage.
