Yttrium iron garnet material and preparation method thereof
The invention provides a yttrium iron garnet material and a preparation method thereof. The chemical composition of the yttrium iron garnet material is BiaCabZrcTidYmFinO11.9, 0.6 < = a < = 1, 0.2 < = b < = 0.7, 0.2 < = c < = 0.6, 0.03 < = d < = 0.07, 1.4 < = m < = 2.2, and 4.1 < = n < = 4.7. The preparation method comprises the following steps: weighing the raw materials converted according to the chemical composition, carrying out primary ball milling, drying, pre-sintering, sieving, carrying out secondary ball milling, adding a binder, drying, pressing into a green body, and sintering; the saturation magnetization of the yttrium iron garnet material disclosed by the invention is above 1700Gs, and the yttrium iron garnet material can meet relatively high use frequency; meanwhile, the dielectric constant of the material is adjustable in the range of 21.4-35, and microwave devices with different size requirements can be met; pr, Hf and other precious metals do not need to be used in the material, the formula cost is low, and large-scale industrial production is facilitated.
本发明提供了一种钇铁石榴石材料及其制备方法，钇铁石榴石材料的化学组成为BiaCabZrcTidYmFenO11.9，0.6≤a≤1，0.2≤b≤0.7，0.2≤c≤0.6，0.03≤d≤0.07，1.4≤m≤2.2，4.1≤n≤4.7；制备方法包括称取按上述化学组成换算的原材料，一次球磨，烘干，预烧，过筛后，二次球磨，加入粘结剂，烘干，压制成生坯后烧结；本发明的钇铁石榴石材料饱和磁化强度在1700Gs以上，能够满足较高的使用频率；同时，本发明的材料介电常数在21.4‑35范围内可调，能够满足不同尺寸需求的微波器件；本发明的材料不需要使用Pr、Hf等贵金属，配方成本较低，利于大规模工业化生产。
