High-purity aluminum oxide ceramic shaft and preparation method thereof
The invention belongs to the technical field of ceramic materials and specifically relates to a high-purity alumina ceramic shaft and a preparation method thereof. The high-purity alumina ceramic shaft comprises a ceramic shaft body, wherein the ceramic shaft body comprises a hollow cylinder; the length of the ceramic shaft body ranges from 90.4 mm to 90.6 mm; the inner diameter of the ceramic shaft body is 6mm; circular wings are arranged on the ceramic shaft body; the wings divide the ceramic shaft body into an upper part and a lower part; the length of the upper part is 19.90-20.10 mm, theouter diameter of the upper part is 24.96-24.98 mm, the length of the lower part is 62.5-62.6 mm, the outer diameter of the lower part is 24.96-24.98 mm, and the outer diameter of the wings is 38.40-38.60 mm; and the upper part is a cylindrical cutting body of which one side of a cylinder is cut by a vertical plane, and one side of the upper part is a vertical rectangular surface. According to theceramic shaft, the purity of aluminum oxide is 5N, water for granulation is high-purity water with the conductivity of 0.06 S/M, the purity of aluminum oxide is high, and the particle size distribution curve is narrow, so that the ceramic shaft is high in oxidation resistance, good in wear resistance, high in high-temperature and low-temperature thermal expansion and cold contraction resistance and has the functions of vibration resistance, acceleration impact resistance, water resistance, acid corrosion resistance and the like.
本申请属于陶瓷材料技术领域，具体为一种高纯氧化铝陶瓷轴及其制备方法，包括陶瓷轴本体，陶瓷轴本体包括空心的圆柱体，陶瓷轴本体的长度为90.4‑90.6mm，所述陶瓷轴本体的内径为6mm，陶瓷轴本体上设有圆环形的翅膀，翅膀将陶瓷轴本体分为上下两部分，上部分的长度为19.90‑20.10mm，上部分的外径为24.96‑24.98mm，下部分的长度为62.5‑62.6mm，下部分的外径为24.96‑24.98mm，所述翅膀的外径为38.40‑38.60mm；所述上部分为圆柱体一侧被竖直平面截切的圆柱截切体，所述上部分的一侧为竖直的矩形表面。本申请所述的陶瓷轴是用氧化铝纯度为5N，造粒用水是电导率为0.06S/M的高纯水，氧化铝纯度高，粒度分布曲线窄，因此抗氧化能力强，耐磨性好，抗高低温热涨冷缩能力强，并具有抗震动、抗加速度冲击、耐水、耐酸侵蚀等功能。
