Abstract
Metodo esperimental eta marko teoriko bat deskribatu ditugu, material zeramikoen tenperatura altukopropietate optikoak aztertzeko. Metodo honen gaitasuna erakusteko, boro nitrurozko (BN) bi materialenemisibitate infragorria neurtu dugu. Material hauen propietate optikoak espektro infragorrian ezagutzeabeharrezkoak dira hainbat aplikaziotarako (pirometria eta sateliten estaldurak, adibidez). Eredu teori-koek, konposizio kimikoa eta egitura kontuan hartuz, espektro esperimentalen arteko desberdintasunakazal ditzake.
We describe an experimental method and a theoretical framework for the study of the optical propertiesof ceramics at high temperature. We show the capability of this method by measuring and interpretingthe infrared emissivity of two boron nitride (BN)-based materials.Knowledge of the infrared opticalproperties of these materials is necessary for several applications, from pyrometry to solar coatings insatellites.Besides, the theoretical framework can explain the differences among experimental spectrataking into account the effects of chemical composition and structure.
