“…The cooling trace method was used for the determination of liquidus temperatures in the (Lu,Y,Gd,Nd,La) 2 O 3 system and consists in melting samples and recording their temperature upon cooling. A temperature peak during cooling indicates the recalescence phenomenon, and the peak maximum is assigned as the sample liquidus temperature [25]. The optical pyrometers are commonly used to measure such high temperature, and the spectral emissivity of the sample should be known for accurate measurements.…”

“…The mPD method is ideally suited for this study due to the relatively small amounts of expensive starting materials (~1 g) and faster growth rates that can be achieved compared to scalable techniques such as the Czochralski method [24]. The minimization of the T m in composition 3 is demonstrated via the cooling trace method [25].…”

“…For multicomponent systems, liquidus and solidus temperatures can be extracted, but is more difficult and requires more statistics. Liquidus temperatures in oxide systems that have been examined include HfO 2 -Ta 2 O 5 (up to 3200 K), 30,31 (Fe,Cr,Al) 3 O 4 spinels with variation in oxygen partial pressure (up to 2000 K), 32 and others. 33,34 Drop-and-catch calorimetry utilizes ADL via a CNL with a split nozzle and laser heating to achieve temperatures up to 3700 K. Once the sample has equilibrated, the split nozzle is opened, allowing the high-temperature sample to fall and be caught between two copper heat sinks maintained at 298 K that are attached in series to two semiconductor heat flux transducers (Figure 1d-e).…”
