Preparation method of dielectric ceramic material
The invention relates to the technical field of ceramic materials, and discloses a preparation method of a dielectric ceramic material, which comprises the following steps: mixing raw materials of lanthanum oxide, aluminum oxide, titanium dioxide, magnesium oxide and calcium carbonate with deionized water, conducting grinding to form slurry by using a ball mill, conducting filtering and dehydrating, conducting drying and crushing to form a powder, conducting pre-sintering, and conducting ball-milling again to obtain secondary slurry; and continuously adding an adhesive, conducting stirring, conducting granulating, carrying out compression molding, conducting heating and plastic removing, and finally, feeding the molded material into a sintering furnace for sintering. The dielectric ceramic material prepared by the method has lower porosity, higher quality factor and a frequency temperature coefficient close to 0, and is suitable for the communication field, such as antennas, Monoblocks, RFID (Radio Frequency Identification), filters and the like.
本发明涉及陶瓷材料技术领域，公开了一种介质陶瓷材料的制备方法，包括将原材料氧化镧、三氧化二铝、二氧化钛、氧化镁与碳酸钙与去离子水混合，用球磨机磨成浆料，再过滤脱水、烘干并破碎成粉料，随后预烧结，再次球磨得到二次浆料，继续加入粘合剂并搅拌进行造粒、模压成型、加热排塑，最后将成型材料送至烧结炉中烧结。这种方法制得的介质陶瓷材料具有较低的气孔率、较高的品质因数与接近0的频率温度系数，适用于通讯领域，例如天线、Monoblock、RFID、滤波器等。
