Sintered bodies of Zr2WP2O12 (ZWP) and ZrV0.6P1.4O7 (ZVP) were fabricated, and their linear thermal expansion coefficients (TEC) were found to be -2.92 × 10-6 and 3.27 × 10-6 °C-1, respectively, in the range 25-500 °C. In an attempt to fabricate composites with a zero-thermal-expansion property, sintered ZWP/ZVP composites with ZVP/ZWP volume ratios of 0.5/0.5, 0.53/0.47, 0.55/0.45, and 0.6/0.4...

Recently, we have introduced a novel, material-independent processing method for producing macro porous ceramics with capillary suspensions as a stable precursor. A capillary suspension is a three-phase system where a small amount of an immiscible secondary liquid is added to a suspension resulting in the formation of a sample spanning particle network. This technology provides open porosities ...

Purpose An integral component in heat pipes (HPs) and vapor chambers (VCs) is a porous wicking structure. Traditional methods for manufacturing structures within HPs VCs involve secondary processes are generally limited to simple geometries. This work aims leverage the unprecedented level of design freedom laser powder bed fusion (LPBF) additive (AM) produce integrated VCs. Design/methodology/a...
