Densities of liquid oxide melts with melting temperatures above 2000 °C are required to establish mixing models in the liquid state for thermodynamic modeling and advanced additive manufacturing and laser welding of ceramics. Accurate measurements o

In the technically important ZrO 2 –SiO 2 phase system we studied liquid phase formation and solidification by means of the containerless aero acoustic levitation preventing contamination by contact to crucible material. The behaviour of the melt w

Das technisch wichtige pseudobinare System ZrO2-SiO2 wurde im Liquidus-Bereich mittels tiegelfreier aeroakustischer Levitation und Hochgeschwindigkeitskamera hinsichtlich der Mischungslucke untersucht. Das Monotektikum L1 = ZrO2 + L2 bei 2250 °C mit

A new method for the experimental estimation of radiant heat emittance at high temperatures has been developed which involves aero-acoustic levitation of samples, laser heating and contactless temperature measurement. Radiant heat emittance values ar

What determines the mechanical material properties of a material sample after solidification is strongly tied to its microstructure. Nevertheless, the precise laws governing the initial stage of this structuring process, i.e. nucleation and the succe

It is well known that the mechanical material properties of a material sample after solidification are strongly tied to its microstructure structure. Nevertheless, the precise laws governing the initial stage of this structuring process, i.e. nucleat

The phase field theory describing the evolution of a dual phase boundary is extended to multiphase problems: Each phase is identified with an individual phase field and the transformation between all pairs of phases is treated with its own characteri

A new aero-acoustic levitation instrument (AAL) has been installed at the Institute for Mineral Engineering at RWTH University in Aachen, Germany. The AAL employs acoustically stabilized gas jet levitation with laser-beam heating and melting to creat

We derive a generalized model for isotropic as well as anisotropic crystal lattice systems of arbitrary Poisson ratio within the framework of the continuum phase-field crystal (PFC) approach (Elder and Grant 2004 Phys. Rev. E 70 051606). To this end
