Preparation method of matte iron sand gold ceramic glaze
The invention belongs to the technical field of ceramic raw material processing. The invention specifically discloses a preparation method of a matte iron sand gold ceramic glaze. Aluminum hydroxide and an iron oxide compound are introduced into a ceramic glaze formula; the mixture is used as a coloring base pigment; interlayer domain modification is carried out on layered silicate minerals such as kaolin which is one of important raw materials; an aluminum hydroxide color-based powder material and an iron oxide color-based powder material are introduced into a kaolin interlayer; in the high-temperature reduction flame firing process, in-situ reaction is performed with a siliceous component with a layered structure, the growth of a product is limited by a layered structure of minerals, andthus the structure of iron sand metallogenic phase is formed; because various physicochemical properties of the modified kaolin are not greatly changed and the modified kaolin is easily and uniformlymixed with other raw materials in the ball milling process, the iron sand gold crystal phase formed in the high-temperature reduction flame firing process is uniformly distributed in a ceramic product, the surface of the product is matte, and the iron sand gold crystal phase flashes.
本发明属于陶瓷原料加工技术领域，具体公开了一种亚光铁砂金陶瓷釉料的制备方法，在陶瓷釉料配方中引入氢氧化铝和氧化铁化合物，作为着色色基颜料，并通过对生产重要原材料之一的高岭土等层状硅酸盐矿物进行层间域改性，将氢氧化铝色基粉料和氧化铁色基粉料引入高岭土层间，使之在高温还原焰烧成过程中与层状结构的硅质组分发生原位反应，矿物的层状结构限制产物的生长，从而形成铁砂金晶相结构，由于改性后的高岭土各项物理化学性质变化不大，在球磨加工过程中容易与其他原材料混合均匀，因而在高温还原焰烧成过程中形成的铁砂金晶相在陶瓷产品中分布均匀，表面呈亚光、铁砂金晶相闪亮。
