Method for decorating ceramic by using crystalline silicon

Abstract

The invention relates to the technical field of preparation of various ceramic materials, in particular to a method for decorating ceramic by using crystalline silicon. Comprising the following steps: (1) taking crystalline silicon or soaking dried crystalline silicon in a soaking solution, (2) forming a ceramic green body by using the crystalline silicon in the step (1), (3) decorating a ceramic glaze surface by using the crystalline silicon in the step (1), and (4) calcining and forming the ceramic green bodies formed in the steps (2) and (3) in a firing kiln to prepare the crystalline silicon decorative ceramic. Crystalline silicon is adopted for beautifying ceramic, the flashing effect is achieved through the physical characteristics of strong metal color on the surface of a silicon crystal material and strong reflection on light, the decoration performance of a ceramic product is enhanced, meanwhile, the materials are easy to obtain, the process technology is simple and easy to implement, quality is stable, the yield is high, benefits are good, decoration and competitiveness are better, and the ceramic decoration product is wide in firing temperature range. The flash glass is suitable for various firing atmospheres, easy to control, capable of being quickly fired, environment-friendly, energy-saving and outstanding and obvious in flash effect.

Description

technical field [0001] The invention relates to the technical field of preparation of various ceramic materials, in particular to a method for decorating ceramics with crystalline silicon. Background technique [0002] Ceramics is a general term for pottery and porcelain, and it is a product fired with natural silicate such as clay as the main raw material. [0003] Ceramic decoration is a variety of methods and techniques for processing ceramics. Through these methods and techniques, the aesthetic feeling of ceramics is given, the attributes of ceramics are improved and expanded, and ceramics are both practical and artistic. Ceramic decoration includes painting on the glaze, painting under the glaze, carving under the glaze, using various colors of glaze for decoration, and also combining various techniques. This so-called "art of fire", through the combination of modern science, technology and materials, has formed a colorful art form and continuous improvement of product...

AI Technical Summary

Problems solved by technology

This kind of decoration is limited to ceramic glazes. The production process of this kind of glazes is complicated (the frit needs to be fired to match the glaze), and the process control is difficult (it is not good if the glaze layer is too thin or too thick, and the firing temperature is limited to 1120-1180 ℃, can only be fired with oxidizing flame, slow cooling and heat preservation is required, the crystallization temperature is harsh, it is not suitable for fast firing, it will cause inconvenience to production, crystals can only exist in the glaze, the glaze color is monotonous), and the yield rate is low , unable to meet the product requirements for decorative ceramics
