What is it about?
BAS/borosilicate glass composites were made by solid-state method. Adding glass formed stable celsian, prevented cristobalite, reduced porosity, and improved density, strength, and thermal expansion. Dielectric constant rose up to 40% glass. Suitable for structural and electronic uses.

Why is it important?
This work is novel for using borosilicate glass to stabilize celsian while suppressing cristobalite formation in BAS ceramics. This dual phase control simultaneously improved density, strength, thermal expansion, and dielectric properties, offering a tunable composite for structural and electronic applications.
Perspectives
This study offers a practical strategy for tuning BAS ceramics through glass addition. The dual control of celsian stabilization and cristobalite suppression is valuable, and property trends are clearly linked to phase evolution. However, optimal glass content varies by property (30% for thermal, 40% for dielectric), so balancing multiple requirements remains a design challenge worth further exploration.
