Preparation method of ceramic for ceramic sensors

CHEN GENFA

The invention discloses a preparation method of ceramic for ceramic sensors, which comprises the following steps: mixing and grinding the raw materials into powder, calcining, and screening after calcining; mixing and stirring after screening, and injecting into a first mold for molding; bonding a metal net to the inner wall of an outer mold, meanwhile, placing the outer mold into a second mold, injecting raw materials, and obtaining a green body after solidification; and sequentially putting the green body into a heating furnace and a sintering furnace for sintering to obtain a ceramic finished product. According to the preparation method of the ceramic for the ceramic sensors, disclosed by the invention, firstly, through mutual promotion and interaction of various raw materials, the prepared ceramic has good stability and thermal shock resistance; secondly, the metal net is mounted in the ceramic, so that the damaged end can be temporarily connected when the ceramic is broken or damaged, and the safety of the ceramic sensors in use is improved; and thirdly, graphite is filled during preliminary sintering, so that the uniformity of the ceramic during heating can be improved.

本发明公开了一种陶瓷传感器用陶瓷制备方法，包括以下步骤：先将各原料混合研磨成粉，并进行煅烧，煅烧完成后筛分；对筛分后混合搅拌，注入第一道模具成型；将金属网粘接在外模的内壁，同时将外模放入第二道模具中注入原料，凝固后得到胚体；将胚体依次放入加热炉、烧结炉中烧结，得到陶瓷成品。本发明所述的一种陶瓷传感器用陶瓷制备方法，一是通过各种原料之间相互促进、相互作用，使制得的陶瓷具有良好稳定性和抗热震性；二是通过在陶瓷的内部安装金属网，能够在陶瓷发生断裂或损坏时，对损坏的一端进行临时连接，提高陶瓷传感器使用时的安全性；三是通过在初步烧结时填充石墨，能够提高陶瓷受热时的均匀性。
