Sample with poor infrared absorption

Samples with low infrared absorption

With the infrared heating method equipment, materials with high infrared transmittance, such as glass, and materials with high infrared reflectance, such as gold-plated films, have an extremely low infrared heating efficiency and must be heated indirectly.

For example, for a sample like a sheet of glass or a flat sample whose entire surface is covered with a gold plating film, the sample is placed on the SiC sintered sample stage (infrared absorber) and heated.
For powder samples with high infrared transmission, a special carbon with low degassing is used for heating.
