( 1 )通过计算机数字控制机床加工制得嵌件，嵌件的材料为固体石蜡， 该嵌件包括一主体部，和一个突出于该主体部表面的凸起部；
( 2 )提供一注塑模具，该注塑模具包括一中空腔体和一个定位孔，将嵌 件置于注塑模具的中空腔体中 ，并将嵌件的凸起部插入注塑模具的定位孔中 ； 然后合模，将氧化锆、稳定剂和粘结剂混合在一起形成浆料，得到氧化锆陶瓷 坯料，以注塑成型的方式于中空腔体中填充氧化锆陶瓷坯料，氧化锆陶瓷坯料 包覆嵌件的主体部，形成一氧化锆陶瓷结构件坯体，然后进行开模，将氧化锆 陶瓷结构件坯体和模具分离；
( 3 )在 1300°C的烧结温度下烧结氧化锆陶瓷结构件坯体，嵌件气化后， 形成氧化锆陶瓷结构件。 该氧化锆陶瓷结构件具有一个倒扣位。
图 1为本发明实施例 1的氧化锆陶瓷结构件的成型流程图 ，图 2为本发明 实施例 1的氧化锆陶瓷结构件的成型过程示意图 ，其中 "a"为嵌件的主体部 ,"b" 为嵌件的凸起部，在烧结过程中 ，由于烧结温度高于固体石蜡的沸点，嵌件气 化消失，制得的氧化锆陶瓷结构件具有倒扣位结构，成型过程简单。
实施例二
本实施例提供一种氧化锆陶瓷结构件的成型方法，包括以下步骤： ( 1 )通过计算机数字控制机床加工制得嵌件，嵌件的材料为金属钼，该 嵌件包括一主体部，和一个突出于该主体部表面的凸起部；

( 3 )在 1300°C的烧结温度下烧结氧化锆陶瓷结构件坯体，形成氧化锆陶 瓷结构件。 由于嵌件的材料为熔点在 2500°C以上的钼，嵌件在烧结过程不熔 化，氧化锆陶瓷坯料与嵌件结合在一起，得到氧化锆陶瓷结构件，该氧化锆陶 瓷结构件为嵌件与氧化锆陶瓷的组合体。
图 3为本发明实施例 2的氧化锆陶瓷结构件的成型过程示意图 ，从图 3中 可以看出 ，氧化锆陶瓷坯料与嵌件结合在一起，制得的氧化锆陶瓷结构件为嵌 件与氧化锆陶瓷的组合体，嵌件可以提高氧化锆陶瓷结构件的强度和刚度，得 到的氧化锆陶瓷结构件具有天线和与其它零件的连接等特定功能。
