Preparation method of black zirconium oxide powder
The invention provides a preparation method of black zirconium oxide powder, and relates to the technical field of black zirconium oxide powder preparation, and the preparation method comprises the following steps: S1, raw material preparation, S2, surface modification, S3, mixing and grinding, S4, preform formation, S5, sintering, S6, grinding and fine grinding, S7, oxidation, S8, blackening treatment, S9, heat treatment and S10, final treatment, s5, performing illumination treatment and adding a reaction aid in the sintering stage, in the process of S3, controlling the size by using a nano-particle control technology and performing high-pressure sintering, before S4, preparing the composite material, and ensuring that the size of the particles is at a nano level by using the nano-particle control technology. The high-pressure sintering can improve the density at the sintering temperature and the bonding strength of the particles, and the microwave-assisted sintering can improve the sintering rate, reduce the sintering temperature, promote the dense arrangement of the particles and improve the density of the sample.
本发明提供黑色氧化锆粉体的制备方法，涉及黑色氧化锆粉体制备技术领域，包括S1原料准备、S2表面改性、S3混合和磨碎、S4形成预体、S5烧结、S6磨削和磨细、S7氧化、S8黑色化处理、S9热处理、S10最终处理，其中，S4形成预体前使用溶胶‑凝胶法处理，S5烧结阶段进行光照处理并添加反应助剂，S3进行过程中，使用纳米颗粒控制技术控制尺寸并进行高压烧结，S4进行前，还要进行复合材料的制备，使用纳米颗粒控制技术可以确保颗粒的尺寸在纳米级别，而高压烧结可以提高烧结温度下的致密度和颗粒的结合强度，微波辅助烧结可以提高烧结速率，减少烧结温度，促进颗粒的致密排列，提高样品的密度。
