Preparation method of perovskite-like structure ceramic coating
The invention discloses a preparation method of a perovskite-like structure ceramic coating, and particularly relates to the technical field of ceramic coating preparation. Used raw materials (in parts by weight) comprise 8-11 parts of Al2O3, 10-25 parts of SiO2, 20-35 parts of Sm2ZrO7, 30-45 parts of BaCeO3, 40-42 parts of BaUO3, 30-40 parts of La2Ce2O7, 90-120 parts of absolute ethyl alcohol and10-25 parts of acetone. According to the invention, Sm2ZrO7, BaCeO3, BaUO3 and La2Ce2O7 which cannot be decomposed at a high temperature (1500 DEG C) are added into the raw materials of the coating to replace the raw materials which are easy to decompose, so that the thermal stability of the ceramic coating can be improved, the ceramic coating can still insulate heat for a base material at a hightemperature to protect the base material, and the thermal stability of the ceramic coating is not influenced.
本发明公开了一种类钙钛矿结构陶瓷涂层的制备方法，具体涉及陶瓷涂层制备技术领域，所使用原料(按重量份数计)包括Al2O3 8‑11份、SiO2 10‑25份、Sm2ZrO7 20‑35份、BaCeO3 30‑45份、BaUO3 40‑42份、La2Ce2O7 30‑40份、无水乙醇90‑120份、丙酮10‑25份。本发明通过向涂层原料中加入高温条件(1500℃)下不会分解的Sm2ZrO7、BaCeO3、BaUO3和La2Ce2O7代替容易分解的原料，从而能够提高陶瓷涂层的热稳定性，使得该陶瓷涂层在高温的条件下仍然能够为基材隔热，以保护基材，从而能够保障陶瓷涂层的热稳定性不受影响。
