Ceramic Slate Composition Using Colored Glass for Smooth Jade Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large-particle ceramic color-penetrated tiles with a stone-like effect face issues of high cost due to expensive frits and pigments, which cause blurry patterns, bubble formation, and poor surface quality during high-temperature firing, affecting the tile's flatness and aesthetics.
Innovation Solution
Use colored glass fragments instead of frits and pigments, utilizing their high thermal stability to achieve a colored jade effect without dispersion, resulting in a smoother surface with micro-protrusions and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If frits and pigments are used to achieve color-penetrated effect, then color effect is obtained, but cost increases and surface quality deteriorates due to pigment dispersion and bubble formation
Solution Approach 1:
The patent replaces expensive frits and pigments with colored glass waste particles, which are cheaper alternative materials. The glass particles maintain color stability at high temperatures without dispersing like organic pigments, thereby reducing production cost while achieving the desired color-penetrated effect.
Solution Approach 2:
The patent changes the material parameter from organic pigments/frits to inorganic colored glass particles. This parameter change eliminates pigment dispersion issues and bubble formation during high-temperature firing, improving surface quality while reducing cost.
2Quantity of substance
If frits are used for color penetration, then color effect is achieved, but surface flatness deteriorates due to local reactions and shrinkage during high-temperature firing
Solution Approach 1:
The patent substitutes frits with colored glass waste particles that have different thermal properties. The glass particles remain stable during high-temperature firing without causing local shrinkage or subsidence, thereby maintaining surface flatness and manufacturing precision.
Solution Approach 2:
The patent creates a composite system where colored glass particles are embedded in the ceramic matrix. This composite structure provides both color effect and structural stability, preventing surface deformation during firing while achieving the desired aesthetic appearance.
3Quantity of substance
If medium-temperature or low-temperature frits are used, then color effect is obtained, but surface quality worsens due to rapid melting and bubble discharge at high temperature
Solution Approach 1:
The patent replaces temperature-sensitive frits with colored glass particles that have high thermal stability. The glass particles do not rapidly melt or generate excessive bubbles during high-temperature firing, eliminating the harmful bubble formation issue while maintaining color effect.
Solution Approach 2:
The patent changes the thermal parameter of the coloring material from low-melting-point frits to high-temperature-stable colored glass. This parameter change raises the melting point and reduces vapor pressure, preventing bubble formation and surface defects during high-temperature ceramic firing.

Function Achieved in This Case
The ceramic slate with a colored jade effect achieves a flat, polished surface with improved aesthetics and reduced production costs, while maintaining production stability and environmental benefits.
Implementation Method 1
chromium sesquioxide as a main coloring substance. This substance is extremely stable, has a melting point of about 2,266±25° C. and a boiling point of about 4,000° C.
Implementation Method 2
drying and firing the ceramic green body to give a ceramic slate with colored jade effect particles dispersed on the surface of the green body

AI summary
The present invention relates to a ceramic slate with a colored jade effect and a preparation method comprising: pressing and forming raw materials containing a ceramic base material and colored glass fragments to obtain a ceramic green body; drying and firing the ceramic green body to give a ceramic slate with colored jade effect particles dispersed on the surface of the green body; wherein, the colored glass fragments account for 3 wt % to 5 wt % of the ceramic base material. Since colored glass waste instead of frits and pigments is used to prepare the ceramic slate with the colored jade effect, the ceramic slate does not have the phenomenon of pigment dispersion after high-temperature firing, and the surface of the fired ceramic slate shows a shape of micro-protrusion, so that the polished tile surface is smoother and free from pits, resulting in a better tile surface effect.
