Abstract

It has been found that the isomorphic capacity of the Zn_{2 – 2x}Ni_2xSiO₄ solid solution with a willemite structure is 15 mol % Ni. The unit cell parameters of Zn_{2 – 2x}Ni_2xSiO₄ samples in the homogeneity range of the solid solution are nearly independent of the content of dopant х and are close to those of undoped Zn₂SiO₄. It has been shown that the melting point of Zn_{2 – 2x}Ni_2xSiO₄ decreases with an increase in х from 1512°С for х = 0 to 1455°С for х = 0.15. The UV-Vis absorption spectrum and color coordinates of Zn_{2 – 2x}Ni_2xSiO₄ correspond to the blue range, and the color intensity of the pigment increases with increasing nickel content.

具有硅锌矿结构的Zn 2 – 2x Ni 2x SiO 4固溶体的合成及晶体化学，热学和光谱化学性质

摘要

已经发现，具有硅锌矿结构的Zn _{2 – 2 x} Ni _{2 x} SiO ₄固溶体的同晶容量为15 mol％Ni。在固溶体均质性范围内的Zn _{2 – 2 x} Ni _{2 x} SiO ₄样品的晶胞参数几乎与掺杂剂х的含量无关，并且与未掺杂的Zn ₂ SiO ₄接近。结果表明，从1512°С开始，Zn _{2 – 2 x} Ni _{2 x} SiO ₄的熔点随着х的增加而降低。对于х = 0.15，х = 0至1455°С 。Zn _{2 – 2 x} Ni _{2 x} SiO ₄的紫外可见吸收光谱和色坐标对应于蓝色范围，并且颜料的色强度随镍含量的增加而增加。
