Ob2Si4O12

Ob2Si4O12 is a chemical formula representing a borosilicate oxide composition that combines boron, silicon, and oxygen. It is not listed as a recognized mineral in major databases and is generally discussed in theoretical, synthetic, or materials-science contexts as a potential borosilicate framework rather than as a distinct natural species.

In a hypothetical structure, four silicon atoms would form SiO4 tetrahedra that connect through shared oxygen to create a silicate network. Two boron centers would be incorporated as BO3 triangles or BO4 tetrahedra within the same framework, depending on synthesis conditions and the degree of polymerization. The precise arrangement and symmetry would determine whether the phase exists as a crystalline compound or a glassy material. Charge balance would be maintained by the network plus possible interstitial cations or modifiers.

Occurrence and synthesis are not established for Ob2Si4O12 as a natural mineral. It could be investigated or realized only under controlled laboratory conditions, typically by high-temperature solid-state synthesis from SiO2 and B2O3 with fluxes or dopants, while controlling boron volatility and phase separation tendencies.

Properties and potential applications depend on the realized form. As a crystalline or glassy borosilicate, Ob2Si4O12 would be expected to exhibit attributes common to borosilicate materials, such as chemical durability and thermal stability, making it of interest for ceramic or glass research if a stable phase can be produced.
