High-energy-storage high-breakdown bismuth ferrite-strontium titanate-based ceramic material and preparation method thereof
The invention discloses a preparation method of a high-energy-storage and high-breakdown bismuth ferrite-strontium titanate-based ceramic material, which comprises the following steps: mixing raw materials according to (0.6-x) BiFeO3-0. 4SrTiO3-xBi (Zr0. 5Zn0. 5) O3-0. 1 wt% MnO2, with x representing molar percentage, x = 0-0.04, and x is not equal to 0; pouring the powder into a mold for compression molding to obtain a green body; performing compression molding on the green body through cold isostatic pressing; calcining the formed green body at high temperature, then cooling to room temperature along with a furnace, sintering into ceramic to obtain dielectric ceramic with high breakdown, polishing and ultrasonically cleaning the dielectric ceramic, and coating the surface of the dielectric ceramic with silver electrode slurry for performance characterization; the material has high breakdown strength and high energy storage density, is simple in preparation process, low in material cost and environment-friendly, and becomes an important candidate material which is excellent in technology and economy and serves as a high-end industrial application material instead of a lead-based ceramic material.
本发明公开了一种高储能高击穿的铁酸铋‑钛酸锶基陶瓷材料的制备方法，包括：按照(0.6‑x)BiFeO3‑0.4SrTiO3‑xBi(Zr0.5Zn0.5)O3‑0.1wt％MnO2将原料混合，其中x表示摩尔百分比，x＝0～0.04，且x≠0；将粉体倒入模具当中压制成型，得到坯体；将坯体通过冷等静压压制成型；将成型的坯体高温煅烧，然后随炉冷却至室温烧结成瓷，得到具有高击穿的电介质陶瓷，对其进行打磨、超声清洗后在其表面涂覆银电极浆料进行性能表征；该材料具有高击穿强度和高储能密度，且本发明制备工艺简单，材料成本低，绿色环保，成为替代铅基陶瓷材料用作高端工业应用材料在技术和经济上兼优的重要候选材料。
