Lanthanum oxide particles as well as preparation method and application thereof
The invention relates to the technical field of powder forming, and discloses lanthanum oxide particles as well as a preparation method and application thereof. The purity of the lanthanum oxide particles is greater than or equal to 95%, and the crushing strength of the lanthanum oxide particles is 80-150N/particle. The lanthanum oxide particles provided by the invention are high in mechanical strength, smooth in surface, regular in shape and easy to store, and when the lanthanum oxide particles are used for preparing a methane oxidative coupling catalyst, the catalytic activity of the catalyst can be remarkably improved.
本发明涉及粉体成型技术领域，公开了一种氧化镧颗粒及其制备方法和应用。氧化镧颗粒的纯度≥95％，氧化镧颗粒的压碎强度为80‑150N/粒。本发明中提供的氧化镧颗粒，机械强度大，表面光滑，形状规整，易于存放，用于制备甲烷氧化偶联催化剂时，可显著提升催化剂的催化活性。
