Hafnium tantalum oxide ceramic powder as well as preparation method and application thereof
The invention discloses hafnium tantalum oxide ceramic powder as well as a preparation method and application thereof. The preparation method of the hafnium tantalum oxide ceramic powder comprises the following steps: 1) respectively adding a metal ion strong coordination agent into a hafnium source solution and a tantalum source solution, heating and mixing, mixing the two solutions, adding a metal ion weak coordination agent, adding a mixture of an organic solvent and water, and heating and refluxing to obtain an HTO precursor solution; and 2) removing the solvent from the HTO precursor solution, and then curing and calcining to obtain the hafnium tantalum oxide ceramic powder. The preparation method of the hafnium tantalum oxide ceramic powder has the advantages of being simple in process, short in period, wide in raw material source, low in requirement for equipment and the like, the prepared hafnium tantalum oxide ceramic powder has metal element dispersity at the molecular level and high sintering activity, single-phase Hf6Ta2O17 ceramic with stable crystal configuration can be successfully sintered at 800 DEG C within a short time, and the hafnium tantalum oxide ceramic powder is suitable for industrial production. The application prospect is wide.
