Low-temperature synthesis of berlinite-bonded alumina ceramics.

PDF Version Also Available for Download.

Description

Alumina ceramics, in which berlinite (aluminum orthophosphate, AlPO{sub 4}) is the bonding phase, were synthesized at 150 C. Differential thermal analysis of a mixture of Al{sub 2}O{sub 3} and H{sub 3}PO{sub 4} solution indicated that a minimum temperature of 118 C was necessary for a chemical reaction to occur. Therefore, we hydrothermally cured a mixture of Al{sub 2}O{sub 3} and H{sub 3}PO{sub 4} solution between 130 C and 150 C to form a hard and dense berlinite-bonded alumina ceramic. The intermediate phase of aluminum phosphate hydrate (AlH{sub 3}(PO{sub 4}){sub 2}H{sub 2}O) was also identified. Physical and mechanical properties of this ... continued below
