Development and optimization of lithium aluminosilicate glass-ceramic materials with high β-spodumene content for armor protection

Abstract

This paper presents lithium aluminosilicate glass‑ceramics with up to 80% β‑spodumene developed using optimized compositions and a two‑stage heat treatment. The materials exhibit high hardness (8.5–9.0 GPa), optimal elasticity (318–324 GPa), fracture toughness (8.0–8.4 MPa·m^0.5), and low density (2400–2420 kg/m³), making them promising for lightweight armor.
