Color-changeable high-temperature sintered colored ceramic material and preparation method thereof
The invention discloses a color-changeable high-temperature sintered colored ceramic material and a preparation method thereof, the color-changeable high-temperature sintered colored ceramic material comprises 20-30% of nano zirconium oxide powder, 65-75% of nano aluminum oxide powder and 1-5% of rare earth oxide, the rare earth oxide is one or more rare earth oxides, the rare earth oxide is doped in the powder of the nano zirconium oxide and aluminum oxide material, and the rare earth oxide is doped in the powder of the nano zirconium oxide and aluminum oxide material. Through ultra-high temperature sintering, rare earth oxide is solidly melted to oxide crystals and is enriched on a crystal boundary, so that different absorption energies are generated under the irradiation of light rays with different wavelengths, and the color-changeable colored ceramic is formed; meanwhile, different color change effects can be presented by adjusting the components and the proportion of the rare earth oxide according to requirements, and the diversity of styles of colored ceramic products can be enriched.
本发明公开了一种可变色高温烧结彩色陶瓷材料及其制备方法，包括20%‑30%的纳米氧化锆粉体、65%‑75%的纳米氧化铝粉体、1%‑5%的稀土氧化物，稀土氧化物为一种稀土氧化物或多种稀土氧化物，在纳米氧化锆及氧化铝材料的粉体中掺杂稀土氧化物，通过超高温烧结，使稀土氧化物固熔到氧化物晶体并富集在晶界上，从而在不同波长光线照射下，产生不同吸收能量，从而出现可变色彩色陶瓷；同时，可以根据需要，通过调整稀土氧化物的成分和比例，呈现不同的色彩变化效果，可以丰富彩色陶瓷产品样式的多样性。
