Abstract

A ZrO（NO

）

·2H

O ceramic matrix composite is fabricated by using heating alcohol-aqueous solution and freeze-drying met hod with ZrO（NO

）

·2H

O and tetragonal ZrO

whisker as start materials. The effects of tetragonal ZrO

whisker on the phase composition

microstructure

thermal conductivity and compressive strength of porous ZrO

2(w)

/ZrO

composite are investigated. The results indicate that ZrO

whisker could restrain the transformation of ZrO

from tetragonal to monoclinic effectively. When the sintering temperature

is 1 100℃

porous ZrO

2(w)

/ZrO

composite is composed of tetragonal phase

and ZrO

ceramic is composed of monoclinic phase. The thermal conductivity of porous ZrO

2(w)

/ZrO

composite is far less than that of porous ZrO

ceramic. And the compressive strength of porous ZrO

2(w)

/ZrO

composite is much higher than that of porous ZrO

ceramic.
