Preparation of 14Ce-TZP ceramic powder by co-precipitation method

There are several methods to prepare the above powder, but precipitation and co-precipitation methods are usually used to manufacture high performance ceramics in electronic applications and uranium dioxide in the nuclear material technology. Based on the rule that stipulates requirements of major physico-chemical characteristics of the ceramic powder and feasibility of practice development, operating conditions for preparing 14Ce-TZP ceramic powder are calculated and verified by using continuous stirred tank reactor in continuous operation mode. The obtained ceramic powder has typical physical behaviors such as filterability, compressibility, sinterability, average particle size (APS), specific surface area (SSA) and distribution form of particle size similar to that of UO2 powder used in the nuclear material production. The density of final ceramics made of the powder is in the range of 5.82 - 5.88, equivalent to 97 - 98% TD. (author)
