Wear-resistant ceramic, preparation method thereof and ceramic valveless pump
The invention discloses a wear-resistant ceramic, a preparation method thereof and a ceramic valveless pump, inorganic raw materials of the wear-resistant ceramic comprise hafnium oxide, yttrium oxide and zirconium oxide, the total content of hafnium oxide and yttrium oxide in the inorganic raw materials does not exceed 10wt%, and the balance is zirconium oxide. The preparation method of the wear-resistant ceramic comprises the following steps: step 1, taking inorganic raw materials, mixing, and grinding the inorganic raw materials (a centrifugal machine can be adopted for mixing, so that the moisture of the inorganic raw materials can be removed as much as possible); 2, adding a binder into an inorganic raw material, and uniformly mixing to obtain raw material mud; 3, the raw material mud is formed through a mold to obtain a blank (hydraulic extrusion is adopted during mold pressing, and therefore gaps between crystal phases can be reduced with larger force); and 4, firing the blank to obtain a finished product. The prepared wear-resistant ceramic is high in hardness and good in wear resistance.
本发明公开了一种耐磨陶瓷及其制备方法与陶瓷无阀泵，耐磨陶瓷的无机原料包括氧化铪、氧化钇和氧化锆，且无机原料中氧化铪和氧化钇的总含量不超过10wt％,而余量为氧化锆，而耐磨陶瓷的制备方法包括如下步骤：步骤1：取无机原料进行混合，混合对无机原料进行研磨(可采用离心机进行混料，这样可尽可能的除去无机原料的水分)；步骤2：向无机原料中加入粘结剂并混匀得到原料泥；步骤3：将原料泥通过模具成型得到坯件(在磨具压制时宜采用液压挤压，这样可更大力度的来减小晶相之间的间隙)；步骤4：将坯件进行烧制得到成品。所制得的耐磨陶瓷的硬度高，耐磨性能好。
