Verfahren zur Herstellung von keramischen Pulvern |
摘要 |
The process for preparing ceramic powder having a core-shell structure by dissolving a crystalline ceramic powder in water so as to leave a core portion of the ceramic powder while heating; depositing a component of the ceramic powder dissolved in the water on and around surfaces of the core portion thereof as a deposited material from the water by gradually cooling the ceramic powder and the water obtained in the step of dissolving; and firing a mixture of the ceramic powder obtained in the step of depositing with an additive at a high temperature to subject the deposited material and the additive to solid phase reaction to form a shell portion on and around the core portion of the ceramic powder. The process can produce the ceramic powder having a core-shell structure from a crystalline ceramic powder, thereby achieving high electrical and mechanical features when formed into ceramic electronic parts. |
