B2H4Na2O14Si4 is a complex, wide-band-gap insulating compound containing boron, hydrogen, sodium, oxygen, and silicon.
About B2H4Na2O14Si4
B2H4Na2O14Si4 is a complex inorganic compound composed of boron, hydrogen, sodium, oxygen, and silicon. As a wide-band-gap insulator, it exhibits electronic properties typical of stable dielectric materials, though its current structural data suggests it exists in a metastable state relative to other configurations.
This compound is of interest to researchers investigating the structural diversity of hydrated borosilicates. While its thermodynamic profile indicates it sits above the stability hull, its existence in reported structural databases provides a unique case study for understanding the synthesis and stabilization of complex mineral-like phases.
Key Properties
Cross-validated computational properties for B2H4Na2O14Si4, aggregated across 3 databases.
