Black aluminum oxide ceramic and preparation method thereof
The invention belongs to the technical field of ceramic materials, and particularly relates to black aluminum oxide ceramic and a preparation method thereof. The black aluminum oxide ceramic is prepared from the following raw materials: aluminum oxide and a pigment, the pigment comprises, by mass, 5%-15% of magnesium oxide, 5%-15% of calcium oxide, 5%-20% of silicon dioxide, 20%-40% of chromic oxide, 20%-40% of molybdenum trioxide, 3%-10% of titanium dioxide and 5%-10% of magnesium fluoride, and the mass ratio of the pigment to aluminum oxide is (6-10): (90-94). The black aluminum oxide ceramic prepared through specific proportion adjustment design is low in sintering temperature, the sintering temperature can be 1500 DEG C or below, meanwhile, the four-point bending strength can reach 425 MPa or above, the dielectric loss value can reach the level of 1 * 10 <-4 >, and laboratory verification can reach L: 10 <-12 >; a: 0-2; and b: 0-1.
本申请属于陶瓷材料技术领域，具体涉及一种黑色氧化铝陶瓷及其制备方法。本申请的黑色氧化铝陶瓷，其制备原料包括氧化铝与色料；以质量百分数计，色料包括5%~15%的氧化镁、5%~15%的氧化钙、5%~20%的二氧化硅、20%~40%的三氧化二铬、20%~40%的三氧化钼、3%~10%的二氧化钛以及5%~10%的氟化镁，色料与氧化铝的质量比值为(6~10):(90~94)。本申请通过特定的配比调整设计制备得到的黑色氧化铝陶瓷烧结温度低，能够在1500℃以下，同时四点抗弯强度可以达到425MPa以上，介电损耗值可以达到1*10‑4级别，实验室验证可以达到L:10~12；a：0~2；b：0~1的效果。
