| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a ceramic optical part holding member in which a dimensional change of a sintered body after being subjected to degreasing and sintering processes is small over dimensions of a mold, and a production method thereof. <P>SOLUTION: A lens holder 10 for holding an optical part is made of a silicon nitride ceramic base composite material produced through a process in which silicon and nitrogen are caused to react with each other for nitriding. The silicon nitride ceramic base composite material contains silicon carbide and an iron compound. <P>COPYRIGHT: (C)2011,JPO&INPIT |
