Description
Technical field
The present invention relates to inorganic amorphous technical field of material, more particularly to a kind of low-expansion glass coloured glaze.
Background technology
Coloured glaze is a kind of silicate product, is had a long history, and its quality is glittering and translucent, bright and glittering, change is magnificent,
The exquisiteness of Asians, exquisiteness and implicit are fully demonstrated, is the important decoration element in building, and one in artistic decoration
Wonderful work.The main component of coloured glaze is SiO2(i.e. silica), aluminum oxide, fluxing agent lead oxide and pigment etc..
Coloured glaze composition with softening point it is low, material property a length of good characteristic, be so easy to technique to manufacture, be adapted to coloured glaze shaping, coloured glaze
The quality of glass product is embodied in good luster, and bubble, striped, calculus are few.The softening point of coloured glaze, material property depend primarily on coloured glaze formula
The species and its ratio of middle composition, and fining agent is added in coloured glaze basic ingredient can reduce coloured glaze fusion temperature, melt
Quality is improved, the defects of avoiding producing bubble, striped, calculus.Fining agent can release decomposition in coloured glaze production process
Gas, or itself gasification, produce substantial amounts of bubble, receive the minute bubbles on periphery, rise with blub and promote coloured glaze to clarify.
At present, the thermal coefficient of expansion of existing glass-glaze sulfide glass is larger, when in hot environment or extremely frigid zones use glass
During colored glaze product, due to the expansion of colored glaze product, it is easy to ftracture.But at present on suitable for preparing low-expansion coefficient
Azure stone handicraft, coloured glaze formula best in quality report it is less.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of low-expansion glass coloured glaze, the glass for firing to obtain by the formula
Coloured glaze, its coefficient of expansion is small, can tolerate it is extremely cold very hot, suitable for hot environment and extremely frigid zones.
In order to solve the above-mentioned technical problem, the invention provides a kind of low-expansion glass coloured glaze, including by weight
Following component：Quartz sand 60-77 parts, soda ash 25-33 parts, aluminum oxide 2-5 parts, ceria 1-4 parts, sodium nitrate 0.1-1 parts, carbon
Sour barium 1-4 parts, cordierite powder 20-36 parts, spodumene powder 15-30 parts, lithium carbonate 8-15 parts, fluxing agent 3-8 parts, pigment 0.2-
1.5 part.
Preferably, the pigment is FeO, CuO, TiO2 or Co2O3。
Preferably, the fluxing agent is lithium porcelain stone.
Preferably, the low-expansion glass coloured glaze includes following component by weight：It is quartz sand 65-72 parts, pure
Alkali 28-30 parts, aluminum oxide 3-4 parts, ceria 2-4 parts, sodium nitrate 0.3-0.6 parts, barium carbonate 2-4 parts, cordierite powder 25-35
Part, spodumene powder 20-25 parts, lithium carbonate 10-14 parts, fluxing agent 5-7 parts, pigment 0.5-1 parts.
Preferably, the granularity of the cordierite powder is 1-20 μm, the granularity of the spodumene powder is 5-40 μm.
The low-expansion glass coloured glaze of the present invention, by introducing cordierite powder, spodumene powder and lithium carbonate in formula,
It mutually melts with quartz, aluminum oxide in sintering process and to form the very low Li of the coefficient of expansion2O-Al2O3-SiO2Crystallite and violet
Green stone crystallite, these low-expansion crystallites are distributed in glass-glaze sulfide glass matrix so that the thermal coefficient of expansion of product is lower, can
As little as 0.4-1.2 × 10-6℃-1, anti-extremely cold very hot effect is good, and tolerable -30 DEG C -500 DEG C are not ftractureed once.
