| titleOfInvention | A kind of two-phase cobalt tantalate ceramic block and preparation method thereof |
| abstract | The invention discloses a two-phase cobalt tantalate ceramic block and a preparation method thereof. The two-phase cobalt tantalate ceramic block is composed of Co 4 Ta 2 O 9 and CoTa 2 O 6 , and Co 4 Ta 2 O 9 and CoTa The molar ratio of 2 O 6 is X: (1-X), 1>X>0; the thermal conductivity of the two-phase cobalt tantalate ceramic block is 1.5-2.8Wm-1.K - 1 , and the fracture toughness>2MPa. m 1/2 ; Cobalt oxide and tantalum oxide with high sintering and reactivity are obtained by thermal decomposition, which effectively reduces the temperature required for the reaction to generate Co 4 Ta 2 O 9 and CoTa 2 O 6 dense ceramics, and prevents over-burning and grain size The occurrence of excessive growth allows the two ceramics to react and nucleate at the same low temperature. At the same time, the two cobalt tantalate grains compete with each other for simultaneous crystallization and growth, which plays a role in inhibiting grain growth and improving material density. , obtain a ceramic material with a grain size of less than 10 microns, effectively improve the fracture toughness of the material and reduce the thermal conductivity. |
