本文介绍了高温材料熔点的测试设备和测试方法。熔点炉的温度可达3000℃;采用高精密显微光学高温计测温:在2500—3000℃内温度测定的不确定度为±40℃。 用高纯度的金属样品(钼、锆)对该设备进行了校准,证明其性能良好。
This article describes the high temperature melting point of the test equipment and test methods. Melting point furnace temperature up to 3000 ℃; high precision microscopy optical pyrometer temperature: 2500-3000 ℃ temperature measurement uncertainty of ± 40 ℃. The device has been calibrated with high purity metal samples (molybdenum, zirconium) to prove its performance.
