Description

一种超大尺寸高铝瓷球及其制备方法
技术领域
本发明属于陶瓷材料领域,具体涉及一种超大尺寸高铝瓷球及其制备方法。
背景技术
氧化铝陶瓷球是生产规模最大,应用领域最为广泛的特种结构陶瓷,具有硬度高、密度大、磨耗小,耐腐蚀和高性价比等特点,被广泛应用在建筑、冶金、化工、电子等领域。国内外生产的高铝瓷球主要是以α氧化铝粉为主要原料,通过球磨、成型和高温烧结等躲到工序制作,成型方式主要有半等静压成型、等静压成型和滚制成型,对于超大尺寸高铝瓷球(尺寸大于300mm)的制备,由于尺寸因素,在等静压成型时,由于需要的压力巨大,对设备的要求非常高,在压力欠缺情况下往往无法成坯,同时在干燥及高温烧结过程中容易造成制品开裂。同时在超大尺寸的高铝瓷球生产中,外观容易出现斑点、起泡、粘损、风晶等缺陷,同时易发生腰裂、生烧、指甲纹等性能缺陷。
发明内容
基于上述背景,本发明提供一种超大尺寸高铝瓷球及其制备方法,工艺流程简单,成品率高,外观光洁,无斑点、气泡、粘损等缺陷。

(2)注模:在步骤(1)制得的球磨浆料中加入悬浮剂搅拌0.8~1.5h,再用注浆管道从一定高度上以一定注浆速率垂直注入石膏模中,所述石膏模垫置在振动电机上,在注浆过程中石膏模始终处于振动状态,模腔初次注满后,调节注浆速率,继续注浆20min后停止,再继续振动30min,静置一端时间后出模,制得粗坯;
优选的,悬浮剂的添加量为球磨浆料质量的1~3%,注浆高度为3~5米,注浆速率为450~550g/min,振动频率为50~70次/min,初次注满后注浆速率调节至4~6g/min,静置时间为2~4h;
(3)修坯干燥:将步骤(2)制得的粗坯一端固定在旋转轴上,以300转/min的速度转动,用修坯刀将粗坯修整成规则球型,在将修好的球坯转置于微波干燥炉中,在60~80℃下干燥1~3h后自然冷却;
(4)烧结打磨:将步骤(3)干燥后的坯料置于真空烧结炉中烧结6~8h,烧结温度为1630~1670℃,出炉后自然冷却,再在旋转打磨机上,用2000目水磨砂纸,在水流下打磨光滑,即得到超大尺寸高铝瓷球成品。
与现有技术相比,本发明的有益效果是:制备工艺简单,对设备要求低,制备的高铝瓷球尺寸大,基体致密无孔洞,外观光洁,无斑点、气泡、粘损等缺陷,干燥及烧结过程中不易开裂,成品率高。
