| Research Abstract |
The containerless method with laser heating allowed high-melting-point oxides, e.g. zirconia and ceria, to be measured the melting point within a few 10 ms, and the basic measurement system, which consisted of YAG laser, monochromatic pyrometer, integrating sphere, probe laser and reflected light detector, was developed to simultaneously measure the melting point and the emissivity.
In addition, we confirmed that the sample additionally heated at high temperature (~1000 K) during measurement had the long thermal arrest period and did not break despite the thermal shock. Furthermore, even though the samples, e.g. ceria and alumina, had high transmittance for the wave length of 1064 nm, surface coating with black paint including SiC allowed them to be measured the melting point by YAG laser heating.
