Effect of YF3 on densification behavior and thermal conductivity of AlN ceramics with Y2O3–YF3 additives under reducing atmosphere

Boosting the in-plane thermal conductivity of nanofibrillated cellulose films: alignment engineering of cross-linked AlN whiskers

“…C p is the specific heat capacity of the composite film, which was calculated using the mixing rule, 31–33 as shown below: C p = C AlN × φ + C NFC × (1 − φ )where φ is the volume fraction of AlN; C AlN and C NFC are the room temperature specific heat capacities of AlN and NFC, which were determined using a TAQ600 differential scanning calorimeter (DSC) and measured as 0.51 J g −1 K −1 and 1.46 J g −1 K −1 , respectively. The relationship between the mass fraction and volume fraction of AlNw in the composite films is shown in Table S1,† where the densities of AlN and NFC were taken as 3.26 g cm −3 and 1.48 g cm −3 , 34,35 respectively. The surface temperature variations of the composite films during actual application were recorded using an E8-XT infrared thermal camera (FLIR).…”
