Wear-resistant and high-temperature-resistant material for nebulizer and its preparation method

Abstract

A wear-resistant and high-temperature-resistant material for a nebulizer and its preparation method, the nebulizer material comprises zirconia ceramic powder, silicon nitride, tungsten carbide, yttrium oxide, aluminum oxide, and a sintering aid in specific weight parts. The preparation method comprises steps of raw material pretreatment, mixing and ball milling, forming, sintering, and post-treatment. The nebulizer material, through composite modification, combines high toughness, high-temperature resistance, and high wear resistance. It can withstand high temperatures of 300-600°C, and its wear rate is reduced by more than 60% compared to conventional materials. The material exhibits excellent chemical stability with no release of harmful components, complies with medical material safety standards, and is suitable for preparing a nebulizer nozzle and a nebulizer nebulization chamber, it can significantly enhance the service life of the nebulizer, meeting both clinical and home use demands.
