摘要：【中文】本发明公开了一种高温吸收剂、超薄高温吸波材料及其制备方法，先按照化学计量比称取TiO₂、SrCO₃和Gd₂O₃，混合后依次进行球磨、干燥、研磨、过筛，并将物料升温至1200～1350℃保温处理2～3.5h进行预烧并随炉冷却，制得分子式为Sr_1‑xGd_xTiO₃的吸收剂。然后按照(1:9)～(4:6)的质量比称取Al₂O₃和Sr_1‑xGd_xTiO₃吸收剂，混合后依次进行球磨、干燥、研磨、过筛，并将物料升温至1250～1400℃高温保压处理1.5～3h进行真空热压烧结，随炉冷却后制得分子式为Sr_1‑xGd_xTiO₃/Al₂O₃，其中0.05≤x≤0.3。解决了现有陶瓷吸波材料厚度较大的问题。 【EN】The invention discloses a high-temperature absorbent, an ultrathin high-temperature wave-absorbing material and a preparation method thereof₂、SrCO₃And Gd₂O₃Mixing, ball milling, drying, grinding and sieving in sequence, heating the materials to 1200-1350 ℃, preserving heat for 2-3.5 h, pre-burning and cooling along with a furnace to obtain Sr with a molecular formula_1‑xGd_xTiO₃The absorbent of (1). Then weighing Al according to the mass ratio of (1:9) - (4:6)₂O₃And Sr_1‑xGd_xTiO₃Mixing the absorbent, ball-milling, drying, grinding and sieving in sequence, and heating the materials to 1250-1400 ℃ for high temperature preservationPressing for 1.5-3 h, performing vacuum hot-pressing sintering, and cooling with the furnace to obtain Sr as a molecular formula_1‑xGd_xTiO₃/Al₂O₃Wherein x is more than or equal to 0.05 and less than or equal to 0.3. The problem of current ceramic absorbing material thickness is great is solved.
