VISUALISATION OF QUANTUM FLUID TWO-FLUID STRUCTURE IN OXIDE MELTS Russian patent published in 2015 - IPC G01N33/00 C01G1/02 C01B35/10 

FIELD: process engineering.

SUBSTANCE: invention can be used in fundamental research and for separation of common fluids and superfluids. Claimed process comprises production of the oxide melt by melting of fine powder of B₂O₃ with additives of BaO or Co₃O₄ at the following ratio: BaO - 1.0 mol %; B₂O₃ - 99.0 mol % or Co₃O₄ - 1.0 mol %; B₂O₃ - 99.0 mol %. Said oxide melt is placed in the cell composed by two concentric platinum crucibles (1, 2) and cured at 1000°C. Them initial solution is spontaneously separated to superfluid (B₂O₃ melt) overflowing into small platinum crucible (1) and initial melt located in larger crucible (2). Superfluid melt represents a boron oxide and is transparent at whatever temperatures while the initial melt with the barium oxide additive turns white milky caused by micro liquation. Identical processes occur at superfluid overflowing in the other oxide melt with the cobalt oxide additive. Here, the initial melt preserves its initial high-intensity blue-violet colour while superfluid melt overflowing into small crucible (1) is completely faded.

EFFECT: possibility of the analysis of properties and marks of boron oxide melts and determination of chemical composition of superfluid melt.
