Abstract | The invention provides a preparation method of rare earth doped ZnAl2O4 nanocrystalline glass. The preparation method comprises the following steps: preparing base glass of the ZnAl2O4 nanocrystalline glass; the base glass is subjected to thermoelectric coupling, and in the thermoelectric coupling process, heating is conducted till glass nucleation is conducted, and then an electric field is applied in the devitrification stage. Aiming at the problem of difficulty in crystal regulation in thermodynamic treatment of glass crystals, an electric field is introduced to obtain spinel glass with different properties; on the basis of heat treatment, the size of nanoscale crystals in spinel is regulated and controlled through a thermoelectric coupling effect, and the light transmittance and the mechanical strength of the glass are regulated and controlled.
本发明提供了一种稀土掺杂ZnAl2O4纳米晶玻璃的制备方法,包括以下步骤:制备ZnAl2O4纳米晶玻璃的基础玻璃;将所述基础玻璃进行热电耦合,所述热电耦合的过程中先加热至玻璃成核再于析晶阶段施加电场。本申请针对热力学处理玻璃晶体存在晶体调控困难的问题,引入电场来获得不同性能的尖晶石玻璃;在热处理的基础上通过热电耦合作用调控尖 |
