Stannic oxide electrode ceramic material as well as preparation method thereof
The invention relates to a stannic oxide electrode ceramic material as well as a preparation method thereof. The stannic oxide electrode ceramic material comprises the following components in parts by weight: 100 parts of stannic oxide, 0.1-0.3 part of copper oxide as an additive, 0.1-0.5 part of zinc oxide, 1.2-1.5 parts of antimonous oxide, 0.8-1.5 parts of bismuth subcarbonate and 3-5 parts of a sodium silicate aqueous solution. The preparation method comprises the following steps: fully mixing and stirring the raw materials; molding at a high pressure in isostatic pressing; sintering at a high temperature of 1500 DEG C by adding inert gas to prepare a stannic oxide electrode ceramic body with high density (over 6.5); and then machining to prepare a stannic oxide electrode. The stannic oxide electrode is an indispensable electrode material for producing high performance optical glass. The preparation method provided by the invention is simple in process, easy to operate, short in production period, low in production cost, stable and reliable in product quality and suitable for industrial production.
