MATERIAL FOR TEMPERATURE COMPENSATION, AND OPTICAL COMMUNICATION DEVICE |
| 摘要 |
A material for temperature compensation comprises a polycrystalline material containing a solid solution of beta -quartz or beta -eucryptite as a main crystal, and it has a negative coefficient of thermal expansion. The interplanar spacing of crystal planes giving a main peak in X-ray diffractometry is less than 3.52 angstroms.
