Ceramic powder, ceramic yarn guide prepared from ceramic powder and preparation method of ceramic yarn guide
The invention relates to ceramic powder, in particular to a 3Y-ZrO2 ceramic yarn guide taking praseodymium oxide Pr6O11 as an additive, which belongs to the field of textile machinery. The ceramic powder comprises 3Y-ZrO2 powder and an additive Pr6O11, and the additive Pr6O11 and the 3Y-ZrO2 powder respectively account for 3-8wt% and 92-97wt% of the total mass of the ceramic powder. According to the ceramic powder used by the ceramic yarn guide, the additive Pr6O11 is added into 3Y-ZrO2 powder; and through step-by-step thermal degreasing and high-temperature sintering, the aging phenomenon ofthe 3Y-ZrO2 ceramic is significantly improved, the toughness and wear resistance of the ceramic are also improved, the service life is greatly prolonged, and the production cost is also reduced.
本发明涉及一种陶瓷粉体，具体涉及一种由氧化镨PrO作为添加剂的3Y‑ZrO陶瓷导丝器，属于纺织机械领域。所述的陶瓷粉料包括3Y‑ZrO粉料和添加剂PrO，其中添加剂PrO与3Y‑ZrO粉料分别占陶瓷粉料总质量的3‑8wt％与92‑97wt％。本发明陶瓷导丝器使用的陶瓷粉体在3Y‑ZrO粉料中加入添加剂PrO，并通过分步热脱脂以及高温度的烧结，显著改善了3Y‑ZrO陶瓷存在的老化现象，也改善了陶瓷的韧性和耐磨性，大大延长了使用寿命，还降低了生产成本。
