Abstract

An arc imaging furnace has various advantages as an apparatus for ceramic synthesis. However, the disadvantage of this furnace is the difficulty of in situ temperature measurement of the sample, because of a very small heating spot in the furnace and the effect of infrared radiation from the light source on the measurement, a monochromatic radiation pyrometer is used. In this paper, a technique for in situ temperature measurement by monochromatic radiation pyrometer is proposed and applied to the melts of a CaO-SiO2 system above 1700°C. Heating up was performed in an arc imaging furnace equipped with a Xenon lamp. The monochromatic radiation pyrometer was proven to work appropriately for in situ temperature measurement of the melting samples above 1750°C, because it can focus on a small melting drop 2-3 mm in diameter, and also because it can avoid the effect of infrared radiation from the Xe lamp, by using a 5 μm wavelength to detect the radiation from the sample melts.
