Thermal and mechanical properties of fibrous zirconia ceramics with ultra-high porosity

Anisotropic properties of highly textured porous alumina formed from platelets

“…Porous ceramics have shown promise as functional materials such as filters [1][2][3], catalysts [4], insulators [5][6][7][8][9], sound absorbing materials [10,11], bioceramics [12][13][14], and lightweight refractory materials [15,16]. Furthermore, most porous ceramics are morphologically uniform, and have the same properties in all directions.…”

Microstructure, radiative property and thermal shock behavior of TaSi2–SiO2-borosilicate glass coating for fibrous ZrO2 ceramic insulation

“…Recently, porous fibrous ZrO 2 ceramics have been considered candidate materials for thermal insulation under conditions of ultra-high temperatures and in various severe environments owing to their outstanding characteristics, including low density, extreme high-temperature stability and low thermal conductivity [8,9]. Thus, a high emissivity coating must be designed and prepared on the fibrous ZrO 2 ceramic insulation substrate.…”

Fabrication and properties of fibrous porous mullite–zirconia fiber networks with a quasi-layered structure

“…To obtain high compressive strength and low thermal conductivity of porous fibrous ceramics at high temperatures, zirconia fiber can be introduced into the ceramics. Fibrous zirconia ceramics with ultra-high porosities (72%-89%) were fabricated by Sun et al [14], which had a low linear shrinkage at high temperatures (less than 2%), ultra-low thermal conductivity of 0.056-0.16 W/(m K) and high compressive strength of 0.6-13.3 MPa. However, the density of fibrous porous zirconia ceramics was relatively high (0.67-1.72 g/cm 3 ).…”
