VISUALISATION OF QUANTUM FLUID TWO-FLUID STRUCTURE IN OXIDE MELTS

摘要

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 BOwith additives of BaO or CoOat the following ratio: BaO - 1.0 mol %; BO- 99.0 mol % or CoO- 1.0 mol %; BO- 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 (BOmelt) 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.3 dwg, 1 tbl
