Nanostructured Advanced Ceramics (NASTRAC)

NASTRAC项目的目标是通过保留纳米结构来制造具有显著增强性能的大型先进陶瓷部件。这将在项目的试点阶段进行演示。独特的是，目标将主要通过传统的加工路线来实现（例如，粉末悬浮优化，雾化形成颗粒，然后压制/烧结）。合作伙伴的目标是在项目结束后的5年内实现500万至1000万英镑的总销售额增长。目前全球价值170亿英镑的先进陶瓷元件在许多行业中发挥着促进作用。NASTRAC项目将重点关注2个案例研究（阀门的氧化锆插入件和钛酸钡电容器），并在供应链上投入。工作将涉及应用专利技术来制造高固体含量的悬浮液。在传统的成型之后，将使用新的烧制程序（包括微波辅助烧制）来确保纳米结构的保留。最终组件将通过现场测试和/或适当的在职测试进行评估。

The goal of the NASTRAC project is to manufacture bulk advanced ceramic components with significantly enhanced properties delivered via a retained nanostructure. This will be demonstrated during the project at a pilot-scale level. Uniquely, the goal will be achieved using largely conventional processing routes (for example, powder suspension optimisation, atomisation to form a granulate and then pressing / sintering). The partners aim to realise a combined increase in sales of £5-10M over 5 years from project end. Advanced ceramic components, currently worth £17B worldwide, play an enabling role across many sectors. The NASTRAC project will focus on 2 case studies (zirconia inserts for valves and barium titanate capacitors), with inputs along the supply chain. Work will involve applying patented technology to create high solids content suspensions. Following conventional shaping, novel firing schedules (including microwave-assisted firing) will be used to ensure the nanostructure is retained. The final components will be assessed using in-field testing and / or appropriate in-service tests.
