Silicon carbide toughened microwave dielectric ceramic material and preparation method thereof
The invention is suitable for the technical field of dielectric ceramic production, and discloses a silicon carbide toughened microwave dielectric ceramic material, which is prepared from the following raw material components in parts by weight: 48 to 57 parts of magnesium oxide, 33 to 42 parts of silicon oxide, 5 to 10 parts of aluminum oxide, 0.3 to 0.5 part of zirconium oxide, 0.2 to 0.6 part of cerium oxide and 0.02 to 0.1 part of silicon carbide. The invention also provides a method for preparing the silicon carbide toughened microwave dielectric ceramic material. The bending strength and the thermal shock resistance of the ceramic material can be remarkably improved, and the influence of temperature change on the material performance of the ceramic material in an actual use environment is reduced; and the preparation process is simple, low in cost and suitable for industrial large-scale production.
本发明适用于介质陶瓷生产技术领域，公开了一种碳化硅增韧微波介质陶瓷材料，包括以下重量份的原料组分：氧化镁48‑57份、氧化硅33‑42份、氧化铝5‑10份、氧化锆0.3‑0.5份、氧化铈0.2‑0.6份以及碳化硅0.02‑0.1份。还提供了一种制备所述碳化硅增韧微波介质陶瓷材料的方法。能显著提高陶瓷材料的抗弯强度和热震性能，减少陶瓷材料在实际使用环境中因温度变化对材料性能所造成的影响；且制备工艺简单，陈本低廉，适用于工业化大规模生产。
