Title (EN) MATERIAL FOR TEMPERATURE COMPENSATION, AND OPTICAL COMMUNICATION DEVICE
(FR) MATERIAU DE COMPENSATION DE TEMPERATURE ET DISPOSITIF DE COMMUNICATION OPTIQUE
Abstract: front page image
(EN)A material for temperature compensation comprises a polycrystalline material containing a solid solution of $g(b)-quartz or $g(b)-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.
(FR)L'invention concerne un matériau de compensation de température comprenant un matériau polycristallin contenant une solution solide de $g(b)-quartz ou de $g(b)-eucryptite en tant que cristal principal, et possède un coefficient de dilatation thermique négatif. L'espacement entre les plans du cristal produisant une crête de diffractométrie des rayons X est inférieur à 3,52 angströms.
