への侵入 窒化アルミニウム（AlN） るつぼ
Aluminum nitride (AlN) is a high-performance non-oxide ceramic material with high thermal conductivity and a low coefficient of thermal expansion, making it an ideal material for molten metal containers. It effectively prevents oxidation contamination of molten metals. After cooling, molten alloys do not adhere to the crucible, allowing for easy removal and improved operational efficiency.

Additionally, AlN ceramics are not wetted by metals such as aluminum (Al) and calcium (Ca) at high temperatures and exhibit outstanding chemical stability with molten uranium. At elevated temperatures, a protective layer forms on the AlN crucible, effectively reducing corrosion. AlN has been confirmed for use as a graphite crucible lining material in uranium melting processes.
