摘要

传统土家族罐罐茶的制作材料往往面临高温性能差、耐久性差等问题。为提高焙茶器具的耐温性和耐用性,本研究提出了一种新型的 TaC 超高温陶瓷。通过粉末冶金技术制备了性能优异的 TaC 陶瓷,包括高能球磨以确保均匀混合,然后进行压缩成型和高温烧结。测试结果表明,该材料具有优异的机械性能,最大深度为 948.67 nm,接触深度为 954.45 nm,抗压性和耐磨性突出。硬度达到 21.4±0.5 Gpa,弹性模量为 397.2±8.7 Gpa,这两项指标都表明其在高负荷下的稳定性。此外,断裂韧性为 2.8±0.2 Mpa*m1/2。在 1000 °C 的高温环境下,TaC 陶瓷的氧化速率常数仅为 0.183 mg2 *cm-4 *h,这表明其具有出色的高温稳定性。这种 TaC 陶瓷的开发不仅强化了土家族茶壶和焙茶茶壶的传统生产工艺,从而提高了产品的使用寿命,而且在其他要求超高温稳定性的工业应用中也具有潜力。这些贡献为陶瓷材料的高温应用提供了新的方向,并为相关产业带来了实实在在的经济和技术价值。

Preparation method and industrialization of Ta-based ultra high temperature ceramic Tujia jar tea baking jar materials
The production materials of traditional Tujia jar tea often face problems such as poor high-temperature performance and poor durability. To improve the temperature resistance and durability of tea baking utensils, this study proposes a new type of TaC ultra-high temperature ceramic. TaC ceramics with excellent performance were prepared through powder metallurgy technology, including high-energy ball milling to ensure uniform mixing, followed by compression molding and high-temperature sintering. The test results demonstrated excellent mechanical properties, with a maximum depth of 948.67 nm and a contact depth of 954.45 nm, proving outstanding compressive and wear resistance. The hardness reached 21.4±0.5 Gpa, and the elastic modulus was 397.2±8.7 Gpa, both of which indicate its stability under high loads. In addition, the fracture toughness was 2.8±0.2 Mpa*m1/2. At a high temperature environment of 1000 °C, the oxidation rate constant of TaC ceramics was only 0.183 mg2 *cm−4 *h, which demonstrates its excellent high-temperature stability. The development of this TaC ceramic not only strengthened the traditional production process of Tujia teapots and tea roasting teapots, thereby improving the product’s service life, but also holds potential for other industrial applications that demand ultra-high temperature stability. These contributions provide new directions for the high-temperature application of ceramic materials and bring tangible economic and technological value to related industries.
