Technical Field

The invention relates to the technical field of ceramic preparation, in particular to a preparation process for preparing a marine ceramic ware by using pottery clay and marine shellfish.

Background

There are significant differences between ceramics and porcelain in appearance and microstructure. Although both consist of 3 components of crystalline material, glassy material and bubbles, the thickness, degree of densification and number of pores are different. The pottery is made mainly of clay raw materials, and has the advantages of simple processing, low firing temperature (generally about 1000 ℃), poor compactness, high porosity and strong water absorption.

Pottery clay is a ceramic raw material. The mineral components are complex, and the silt-sandy clay mainly comprises hydromica, kaolinite, montmorillonite, quartz and feldspar. The chemical composition is similar to that of general clay. Compared with kaolin and bentonite, Al₂O₃Low content of SiO₂、Fe₂O₃The content is higher. It is usually light gray, yellow or purple. It has moderate water absorption, adsorption, plasticity after adding water, and good drying and sintering properties, and can be used for making pottery.

When the pottery clay and other articles are fired together, the other articles need to be specially calcined, so that the pottery clay meets the preparation specification, energy and time are wasted, and the existing pottery production continues the style of the pottery before, and does not form corresponding characteristics.
