The invention discloses a preparation process of a thin-wall and slender product forming raw material with alumina ceramic difficult to form, and relates to the technical field of alumina ceramic preparation, the thin-wall and slender product forming raw material is mainly prepared from the following raw materials in percentage by weight: 93.5% of alumina, 3.99% of silicon dioxide and 2.8% of calcium carbonate, and the specific steps are described in the specification. The preparation method comprises the following steps: step 1, grinding a mixed material; proportioning aluminum oxide, silicondioxide and calcium carbonate; post-proportioning, grinding the proportioned raw materials in a ball mill; wherein the rotating speed of the ball mill is 45-50 revolutions per second; screening the ground mixed powder. After screening is completed, through cooperative use of the aluminum oxide, the silicon dioxide and the calcium carbonate, the mode that in a traditional mode, an adhesive is usedfor pasting is replaced, when the long and thin ceramic is subjected to injection molding, the finished product rate of the ceramic thin wall is high, and compared with the traditional mode, unnecessary waste of raw materials can be effectively reduced.
本发明公开了一种氧化铝陶瓷不易成型的薄壁及细长产品成型原料制备工艺，涉及氧化铝陶瓷制备技术领域，主要由以下重量百分比计的原料制成：氧化铝：93.5％、二氧化硅：3.99％、碳酸钙：2.8％，具体步骤如下所述；步骤一：混合物料的研磨：将氧化铝、二氧化硅、碳酸钙按照上述材料进行配比，配比完成后，将配比好的原料放置在球磨机里进行研磨，球磨机的转速为45～50转/s，将研磨的混合粉末进行筛选，筛选完成后，通过氧化铝、二氧化硅、碳酸钙之间的配合使用，代替了传统方式中利用粘性剂粘贴的方式，在注塑细长陶瓷时，使得陶瓷薄壁的成品率较高，相对于传统的方式来说，其能够有效地提高了减少了原材料不必要的浪费。
