Cold sintering as an enabler for self-healing ceramics: A perspective on sustainable, damage-tolerant materials
Kaveh Rahimi Mamaghani, Nader Parvin · SAGE Publications · 2026
A perspective argues that cold sintering can enable self-healing ceramic architectures and even in-field repair, potentially reducing energy-intensive processing while improving damage tolerance.
Plain English summary
Why this matters
Key findings
- CSP densification is described as achievable at 120°C–300°C using transient solvents and pressure.
- Self-healing ceramics are described as restoring structural/functional integrity via intrinsic oxidation or embedded healing agents.
- The abstract proposes CSP as a route to hybrid healing architectures and as a potential in-field repair technique.
- Key challenges include solvent-agent compatibility, activation energy mismatch, and balancing healing efficiency with mechanical strength.
- A roadmap is outlined emphasizing scalable CSP platforms, multiscale modeling, and lifecycle assessment.
Limitations
This is a Perspective, so the abstract does not provide experimental results, quantitative performance metrics, or demonstrated healing/repair outcomes. It also does not specify which specific ceramic systems, healing agents, or architectures are validated.
