High-solid-content aluminum oxide ceramic granulation powder and preparation method thereof
The invention discloses high-solid-content aluminum oxide ceramic granulated powder and a preparation method thereof. The preparation method of the high-solid-content aluminum oxide ceramic granulated powder comprises the following steps: firstly, testing the water content of dry aluminum oxide powder; weighing the required raw materials for later use according to the proportion and the water content of the aluminum oxide dry powder; the solid content of the aluminum oxide dry powder is 65-80% by mass, and the balance is pure water; sequentially carrying out first-time ball milling and second-time ball milling, and sieving and separating grinding balls and slurry after the second-time ball milling; adding a proper amount of oxalic acid solution into the sieved slurry to adjust the pH value of the sieved slurry to 8.0-9.0; and finally, granulating by a spray dryer, and then sieving by a screen to obtain the aluminum oxide granulated powder with the particle size of 30-60 microns. The slurry disclosed by the invention has relatively high solid content and good flowability, and meanwhile, the aluminum oxide granulation powder has excellent flowability and apparent density, so that the performance of the granulation powder is ensured.
本发明公开一种高固含量氧化铝陶瓷造粒粉及其制备方法，高固含量氧化铝陶瓷造粒粉的制备方法包括如下步骤：首先对氧化铝干粉进行含水率测试；按配比以及氧化铝干粉的含水率称取所需要的原料备用；按质量百分比记，氧化铝干粉的固含量为65‑80％，余量为纯水；然后依次进行第一次球磨和第二次球磨，在第二次球磨后过筛分离磨球与浆料；再将适量草酸溶液添加到过筛后的浆料中，使得过筛后的浆料的PH值调整为8.0‑9.0；最后通过喷雾干燥机造粒，随后采用筛网过筛得到粒径为30μm‑60μm的氧化铝造粒粉。本发明中的浆料具备较高的固含量以及良好的流动性，同时氧化铝造粒粉具备优异的流动性和松装密度，保证了造粒粉的性能。
