以Bi 2 O3和ZrO 2为原料，采用传统固相反应法合成了一种新型环保型无机黄色颜料Bi 4 Zr 3 O 12，并利用紫外-可见反射光谱对其光学性能进行了表征。Bi 4 Zr 3 O 12样品对波长小于450 nm的可见光和紫外光有选择性吸收。结果，Bi 4 Zr 3 O 12样品呈现黄色。在800 °C下合成的样品获得了最鲜艳的红黄色。CIEL*a*B* 体系中的黄度值（B*）与市售的镨黄颜料相当，而红度值（a*）更大。结果表明，Bi 4 Zr 3 O 12颜料的颜色偏红，而不是偏绿的镨黄，因此，Bi 4 Zr 3 O 12颜料应该是一种新型的环境友好型无机红黄色颜料。
Bi4Zr3O12was synthesized as a novel environment-friendly inorganic yellow pigment by a conventional solid state reaction using Bi2O3and ZrO2, and the optical properties of the pigment were characterized by UV-vis reflectance spectroscopy. The Bi4Zr3O12sample selectively absorbed the visible and ultraviolet light at the wavelength shorter than 450 nm. As a result, the Bi4Zr3O12sample exhibited a yellow color. The most vivid reddish yellow color was obtained for the sample synthesized at 800 °C. The yellowness value (b*) in the CIEL*a*b*system was comparable to that of a commercial praseodymium yellow pigment, while the redness value (a*) was larger. Consequently, the color of Bi4Zr3O12was slightly reddish in contrast to that of slightly greenish praseodymium yellow, and, therefore, the Bi4Zr3O12pigment should be a novel environment-friendly inorganic reddish yellow pigment.
