CMAS-corrosion-resistant high-entropy ceramic material with small grain size and preparation method of CMAS-corrosion-resistant high-entropy ceramic material
The invention discloses a CMAS-corrosion-resistant high-entropy ceramic material with a small grain size and a preparation method of the CMAS-corrosion-resistant high-entropy ceramic material, and belongs to the field of thermal/environmental barrier coating materials and preparation of the thermal/environmental barrier coating materials. The preparation method comprises the following steps: solid-phase reaction: carrying out solid-phase reaction on nano SiO2, nano Yb2O3, nano Lu2O3 and any three of nano Y2O3, nano Tm2O3, nano Sc2O3, nano Er2O3 and nano Ho2O3 which serve as raw material powder to generate rare earth disilicate such as (Yb < 0.2 > Tm < 0.2 > Lu < 0.2 > Sc < 0.2 > Er < 0.2 >) 2Si2O7 or rare earth monosilicate such as (Yb < 0.2 > Tm < 0.2 > Lu < 0.2 > Sc < 0.2 > Er < 0.2 >) 2SiO5 or a mixture of the rare earth disilicate and the rare earth monosilicate; the method is simple and easy to implement. The CMAS corrosion resistance of the prepared high-entropy rare earth silicate is obviously superior to that of a single ytterbium silicate material.
本发明公开了一种具有小晶粒尺寸的抗CMAS腐蚀的高熵陶瓷材料及其制备方法，它属于热/环境障涂层材料及其制备领域。制备方法为固相反应：由纳米SiO2、纳米Yb2O3、纳米Lu2O3以及纳米Y2O3、纳米Tm2O3、纳米Sc2O3、纳米Er2O3和纳米Ho2O3中的任意三种为原料粉经过固相反应生(Yb0.2Tm0.2Lu0.2Sc0.2Er0.2)2Si2O7等稀土双硅酸盐或(Yb0.2Tm0.2Lu0.2Sc0.2Er0.2)2SiO5等稀土单硅酸盐或两者的混合物。本方法简单易行。制备出的高熵稀土硅酸盐的抗CMAS腐蚀性能明显优于单一的硅酸镱材料的抗CMAS腐蚀性能。
