Black aluminum oxide ceramic as well as preparation method and application thereof
The invention relates to black aluminum oxide ceramic and a preparation method and application thereof, the black aluminum oxide ceramic contains aluminum oxide and an amorphous phase, and the weight ratio of SiO2 to CaCO3 to MgO to Co3O4 to Mn3O4 to Fe2O3 in the amorphous phase is 1: (0.8-1.0): (0.4-0.6): (1.5-2.3): (2.5-3.0): (2.5-3.0). The black aluminum oxide ceramic disclosed by the invention does not contain toxic elements, and is relatively high in black chromaticity, relatively high in strength and drop weight height and very low in sintering temperature.
本公开涉及一种黑色氧化铝陶瓷及其制备方法和应用，所述黑色氧化铝陶瓷含有氧化铝和无定形相，所述无定形相中SiO2、CaCO3、MgO、Co3O4、Mn3O4和Fe2O3的重量比为1：(0.8‑1.0)：(0.4‑0.6)：(1.5‑2.3)：(2.5‑3.0)：(2.5‑3.0)。本公开的黑色氧化铝陶瓷不含有毒元素，黑色色度较高，强度和落锤高度较大且烧结温度很低。
