Preparation method of zirconia ceramic rod

The invention discloses a preparation method of a zirconia ceramic rod, and belongs to the technical field of ceramic rods. The preparation method comprises the following steps: step 1, adding hydroxyapatite into distilled water, heating to 50-60 DEG C, adding phosphate, stirring, carrying out suction filtration, and drying to obtain modified hydroxyapatite; 2, zirconium oxide, yttrium oxide, titanium oxide, modified hydroxyapatite and an adhesive are mixed, and pug is obtained; and step 3, extruding the pug to prepare a blank, drying and sintering to obtain the zirconia ceramic rod. The preparation raw materials are reasonably matched and selected, the zirconia ceramic rod with high compressive strength and excellent wear resistance is prepared, the cost is low, and industrial production is met. 本发明公开了一种氧化锆陶瓷棒的制备方法，属于陶瓷棒技术领域。该制备方法包括以下步骤：步骤1、将羟基磷灰石加入蒸馏水中，升温至50-60℃，加入磷酸酯进行搅拌，抽滤，干燥，得到改性羟基磷灰石；步骤2、将氧化锆、氧化钇、氧化钛、改性羟基磷灰石和粘合剂进行混合，得到泥料；步骤3、将所述泥料挤出制得坯料，干燥，烧结，得到氧化锆陶瓷棒。本发明通过对制备原料进行合理的搭配与选择，制备出了抗压强度高、耐磨性能优异的氧化锆陶瓷棒，且成本经济，满
