摘要

本文分析了二氧化锆ZrO2改性VK94-1陶瓷的制备工艺，并对其表观密度、机械抗弯强度、维氏硬度（显微硬度）等性能与VK94-1陶瓷进行了比较。研究了样品中二氧化锆含量的变化对上述性能的影响。研究了烧结温度对样品烧结性能的影响。采用等静压机，在150 MPa的压力下对不同组分比的VK94-1/ZrO2（90/10、80/20和70/30）样品进行压制。在1500、1550和1600℃的不同温度下，在不同的烧制介质中进行烧制。

Vacuum-Tight Corundum Ceramics VK94-1 Modified with Zirconium Dioxide

In this article, we analyze the process of obtaining VK94-1 ceramics modified with zirconium dioxide ZrO₂ and determine its properties, such as apparent density, mechanical bending strength, and Vickers hardness (microhardness) in comparison with those of VK94-1 ceramics. The effect of changes in the share of zirconium dioxide in the samples on the above properties is shown. The influence of firing temperatures on the sintering of samples is studied. Samples with different component ratios of VK94-1/ZrO₂ (90/10, 80/20, and 70/30) were pressed using an isostatic pressing machine at a pressure of 150 MPa. Firing was carried out at different temperatures of 1500, 1550, and 1600°C in different firing media.
