Pure black large-size aluminum oxide ceramic structural part and preparation method thereof
The invention discloses a preparation method of a pure black large-size aluminum oxide ceramic structural part, and belongs to the technical field of ceramic materials. The pure black large-size aluminum oxide ceramic structural part is prepared from the following raw materials in percentage by mass: 90-95% of Al2O3, 1.5-7.5% of a coloring agent and 1-2.5% of calcium oxide and/or magnesium oxide, the weighed raw materials are subjected to ball milling treatment, sieved and subjected to dry pressing molding, the temperature is increased to 1580 DEG C at a constant speed by using a common electric furnace, and firing is performed to obtain a pure black aluminum oxide ceramic material. The prepared pure black large-size aluminum oxide ceramic structural part is not less than 20mm in thickness, can reach 20cm-90cm in length and width or diameter size, is uniform in color and luster, is pure black in internal and external consistency, and is high in thermal conductivity and breaking strength. According to the preparation method disclosed by the invention, the pure black aluminum oxide ceramic with consistent inside and outside can be fired without using a special kiln, shielding gas and oxidizing flame, and the preparation method has very good practicability.
本发明公开了一种纯黑色大尺寸氧化铝陶瓷结构件的制备方法，属于陶瓷材料技术领域。本发明纯黑色大尺寸氧化铝陶瓷结构件包含以下质量百分比的原料：90‑95％Al2O3、1.5‑7.5％着色剂、1％‑2.5％氧化钙和/或氧化镁，将称取的各组分原料进行球磨处理后过筛并干压成型，使用普通电炉匀速升温至1580℃烧制，获得纯黑色氧化铝陶瓷材料。本发明制得的纯黑色大尺寸氧化铝陶瓷结构件，厚度不低于20mm，长宽或直径尺寸可达20cm‑90cm，色泽均匀，内外一致纯黑，导热率高，抗折强度高。本发明的制备方法，无需使用特殊窑炉，也不需要在保护气和氧化焰中，就能烧制出内外一致纯黑色的氧化铝陶瓷，具有很好的实用性。
