Problems solved by technology

Among them, the solid-phase sintering reaction method is one of the most commonly used methods for preparing powders, but the composition of the product is prone to deviation, and the single-phase calcination temperature is above 2000 °C
Although the sol-gel method is an ideal and simple method for preparing yttrium oxide nanomaterials, it generally uses expensive alkoxides, which is not conducive to large-scale industrial production.
