High-performance selenium-rich low-expansion ceramic blank and ceramic manufacturing method
The invention relates to the technical field of ceramic materials, in particular to a high-performance selenium-rich low-expansion ceramic blank and a ceramic manufacturing method. A blank comprises 30-40 wt% of petalite, 10-25 wt% of selenium-rich ore, 10-20 wt% of Suzhou soil, 10-20 wt% of Guizhou soil, 6-12 wt% of cordierite, 2-5 wt% of calcined talc, 5-12 wt% of black mud, 1-3 wt% of zirconiumoxide and 0-1 wt% of lanthanum oxide. The method comprises steps: the raw materials of the blank are subjected to ball milling mixing, pressure filtration dewatering, vacuum pugging, moulding, and drying to obtain a blank pug, and then rolling or injection moulding, drying, trimming and water replenishing are carried out, and oxidizing flame slow sintering is carried out to obtain the high-performance selenium-rich ceramic product. The product has good thermal shock resistance, can be suitable for open fire or high-performance selenium-rich ceramic products matched with electric appliances, is formed through the design of a formula system, well meets the use requirements of the selenium-rich ceramic products as cookers, and is beneficial to promoting the technical progress and applicationdevelopment of the selenium-rich ceramic industry.
本发明涉及陶瓷材料技术领域，具体涉及一种高性能富硒低膨胀陶瓷坯料及陶瓷制作方法；胚料的组分为透锂长石30～40wt%、富硒矿10～25%、苏州土10～20wt%、贵州土10～20wt%、堇青石6～12wt%、煅烧滑石2～5wt%、黑泥5～12wt%，氧化锆1～3wt%，氧化镧0～1wt%，坯料各原料组成经球磨混合后，进行压滤脱水、真空练泥、成型、干燥，即得到坯体泥料，经滚压或注浆成型、干燥、修坯补水，采用氧化焰慢烧工艺进行，即获得高性能富硒陶瓷产品；本发明抗热震性能好、能够适用于明火烧或与电器配套的高性能富硒陶瓷产品，通过配方体系的设计，并形成低膨胀陶瓷材料，从而很好地满足富硒陶瓷产品如作为炊具的使用要求，有利于促进富硒陶瓷产业的技术进步和应用发展。
