Overview

About CaBO3

CaBO3 is an intriguing inorganic compound composed of calcium, boron, and oxygen. As a semiconducting material, it represents a unique intersection of alkaline earth metal chemistry and borate structural motifs, drawing interest from researchers investigating novel electronic behaviors in complex oxides.

Despite its existence in multiple reported structures, the compound is characterized as being above the thermodynamic hull, suggesting it is inherently unstable under standard conditions. This metastability makes it a compelling subject for computational studies focused on phase synthesis and structural transformation pathways.
