Luminous ceramic material and preparation method thereof
The invention relates to a luminous ceramic material and a preparation method thereof, and belongs to the technical field of ceramic materials. The preparation method comprises the following steps: preparing a ceramic glaze from potassium feldspar, albite, nepheline, fluorite, quartz, calcium oxide, borax, aluminum oxide, zinc oxide, kaolin, barium carbonate, magnesium oxide and titanium frit, preparing luminescent powder from ZnO, CaCO3, BaCO3, Li2CO3, Al2O3, Ga2O3, SiO2 and Eu2O3, applying the glaze to the surface of a ceramic green body, spraying the luminescent powder to the surface of the glaze, and firing to obtain the luminescent ceramic material. Ga ions in the luminescent powder can enable a crystal phase where luminescent ions Eu are located to be expanded and increased, then the light intensity is improved, and meanwhile the ceramic material is rich in color and long in luminescent afterglow time.
本发明涉及一种会发光的陶瓷材料及其制备方法，属于陶瓷材料技术领域。本发明以钾长石、钠长石、霞石、萤石、石英、氧化钙、硼砂、氧化铝、氧化锌、高岭土、碳酸钡、氧化镁和钛熔块为原料制备陶瓷釉料，以ZnO、CaCO3、BaCO3、Li2CO3、Al2O3、Ga2O3、SiO2、Eu2O3为原料制备发光粉，然后将釉料布施在陶瓷生坯表面，最后将发光分喷涂于釉料表面，经过烧制得到会发光的陶瓷材料。本发明发光粉中的Ga离子可使发光离子Eu所处的晶体相膨胀增大，进而使光强度获得提高，同时本发明陶瓷材料颜色丰富，发光余辉时间长。
