X-RAY DETERMINATION OF THE STRUCTURE OF GLASS*

X-RAY DETERMINATION OF THE STRUCTURE OF GLASS* BY B.E. WARREN ABSTRACT A method has been developed for analyzing the X-ray diffraction patterns of amorphous solids, and the atomic arrangement in two simple glasses has been completely worked out. In SO2, for example, each silicon is tetra- hedrally surrounded by 4 oxygens at a distance 1.60 A,

Refractometry Introduction

Introduction. A refractometer measures the extent to which light is bent (i.e. refracted) when it moves from air into a sample and is typically used to determine the index of refraction (aka refractive index or n) of a liquid sample.. The refractive index is a unitless number, between 1.3000 and 1.7000 for most compounds, and is normally determined to five digit precision.
