Abstract
En 中文
• Cryolite as core modifier tunes TBA freeze-cast Al₂O₃ pore topology into bone-mimetic structure, 10 wt.% being optimal. • 10 wt.% cryolite sample has synergic strength, thermal conductivity & thermal shock resistance, superior to porous Al₂O₃. • Cryolite-induced gas-liquid mass transfer forms dendritic intra-pore supports, enabling synergistic property optimization.
