The phase change energy storage materials based on paraffin/nano-aluminum nitride were prepared in this study. The thermal stability of the composite materials was determined by differential scanning calorimeter, simultaneous thermogravimetry analysis-differential thermal analysis, and X-ray diffraction techniques. The results of differential scanning calorimeter and X-ray diffraction showed that the thermal performance and structure of the composite materials are stable. The change of latent heat is accredited for thermal energy storage. The thermogravimetry analysis-differential thermal analysis revealed that 3 wt% nano-aluminum nitride added into paraffin increases the flash point by at least 10 ı C.

High compacted aluminum nitride (AlN) substrates were prepared by aqueous tape casting. Aluminium dihydrogen phosphate was used to modify AlN particle surface from hydrolysis during casting process. The absolute value of zeta potential for the AlN particle treated by Al(H 2 PO 4 ) 2 was 60mv at pH ¼ 9. The slurry suitable for tape casting was prepared which possessed shear-thinning behavior and appropriate viscosity. The results showed that the green tapes own excellent properties including high bulk density, uniform pore distribution and low porosity. The samples were fired at 1700 C (lower than melting point of Pt) with pressureless sintering process which can be used to fabricate complex device.

“…This is accomplished by heat treatments that lead to liquid removal by evaporation or migration to concentrate at grain-boundary triple points. Recently, Lin (Lin et al, 2008) studied the effect of reduction atmosphere and the addition of nano carbon powder to enhance deoxidation of AlN parts. The viability of using aqueous media for processing AlN at industrial level is strongly dependent on the final properties, namely thermal conductivity and mechanical properties.…”
