Preparation of borosilicate glasses doped with NiO and CoO colorants using microwave technique

Abstract

This research aims to develop a process for preparing borosilicate glass doped with NiO and CoO using microwave techniques. The study involves preparing glass samples to determine the optimal conditions for microwave melting. The prepared mixture is placed in a crucible, heated in a microwave oven at 1,000 watts for 25 minutes, and then removed after melting. The molten glass is poured into a graphite mold and left to solidify. Once the glass begins to harden, it is removed from the mold and annealed at 500°C for 3 hours. After cooling, the glass is polished to a size of 1.0 × 1.5 × 0.3 cubic centimeters for analysis of various properties, including density, refractive index, light absorption, and color in the CIE Lab system.
