Production of Si3N4 porous beads via carbothermal reduction and nitridation technique

Journal of Asian Ceramic Societies, 2020
Si3N4 porous beads were produced from direct carbothermal reduction and nitridation of spheres composed of carbon+SiO2 mixtures. A simple one–step sol–gel templating technique was used to prepare carbon+SiO2 (molar ratio of carbon/SiO2 was set as 4 ...

A Scalable, Durable, Fire‐Safe All‐Day Passive Radiative Cooling Coating for Sustainable Buildings

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
This study reports a scalable, durable coating that combines a fire‑retardant copolymer adhesive, hollow glass microspheres, and boron oxide to achieve passive radiative cooling with over 94% solar reflectance and >95% mid‑infrared emissivity. The coating maintains performance after UV and rain exposure and exhibits UL‑94 V‑0 fire resistance, enabling ...

Study of a Mixed Alkaline–Earth Effect on Some Properties of Glasses of the CaO-MgO-Al₂O₃-SiO₂ System

Boletín de la Sociedad Española de Cerámica y Vidrio, 2007
In the present work, we studied a “Mixed Alkaline–Earth Effect”, i.e. the non-linear behaviour showed by the glass transition temperature as well as by the compressive strength of glasses of the CaO-MgO-Al2O3-SiO2 system, when a part of the CaO contained
