Spontaneous solidification forming aluminum oxide ceramic material and preparation method of ceramic substrate
The invention relates to a ceramic material, in particular to a preparation method of a spontaneously solidified and formed aluminum oxide ceramic material and a ceramic substrate. The invention relates to a spontaneously solidified and molded alumina ceramic material, which comprises alumina powder, a gelling agent, a dispersing agent and a defoaming agent, the gel agent is ISOBAM104, and the content of the gel agent is 0.3 to 0.5 percent; the dispersing agent is sodium citrate, and the content of the dispersing agent is 0.1 to 0.3 percent; the content of the defoaming agent is not more than 0.1%; the remainder is alumina powder. The spontaneously-solidified aluminum oxide ceramic material provided by the invention does not need expensive equipment, and the shape and thickness of a prepared substrate are controllable. The dispersing agent sodium citrate added in the spontaneous solidification process plays a good dispersion role, the pH does not need to be adjusted in the slurry, the content of the additive in the whole system is small, and the prepared ceramic substrate is large in volume density and high in breaking strength.
本发明涉及一种陶瓷材料，尤其是一种自发凝固成型的氧化铝陶瓷料及陶瓷基板的制备方法。一种自发凝固成型的氧化铝陶瓷料，包括氧化铝粉、凝胶剂、分散剂和消泡剂；所述凝胶剂为ISOBAM104，所述凝胶剂的含量为0.3‑0.5％；所述分散剂为柠檬酸钠，所述分散剂的含量为0.1～0.3％；所述消泡剂的含量不大于0.1％；余料为氧化铝粉。本发明提供的一种自发凝固成型的氧化铝陶瓷料不需要高昂的设备，制备的基板形状、厚度可控。在自发凝固过程中所添加的分散剂柠檬酸钠，起到了很好的分散作用，并且在浆料中不需要调节pH，在整个体系中添加剂的含量少，所制得的陶瓷基板体积密度大，抗折强度高。
