研究目的
Investigating the synthesis of transparent nano-ceramics under ultra-high pressure and their potential applications.
研究成果
The synthesis of transparent nano-ceramics under ultra-high pressure has been successfully demonstrated, showing higher hardness and lower thermal conductivity compared to single crystals. These materials have potential applications in scientific and industrial fields.
研究不足
The synthesis requires ultra-high pressure and high temperature conditions, which may limit the scalability and practical applications. The process is also dependent on the specific properties of the starting glass materials.
1：Experimental Design and Method Selection:
Direct conversion from bulk glass starting materials under pressures higher than ～10 GPa and at high temperatures in Kawai-type Multi-anvil Apparatus (KMA). Rapid nucleation followed by slow crystal/grain growth is utilized.
