In the study of infrared radiation character, different species of tourmaline and Draviteoccurring in pegmatites from Hebei that are different in granularity and heattreatmenttemperature are chose for infrared radiation ratio testing. The result shows:The infraredradiation ratio of tourmaline powder is above 0.80 when the surrounding temperature is 20℃and the testing temperature is below 100℃;Schorl has a close infrared radiation ratio to Dravite,which is higher than Elbaite;No matter to Dravite or Schorl, as the content of ferric oxideincreases, the infrared radiation ratio decreases;tourmaline's size is smaller, its infraredradiation ratio is higher;after tourmaline is heat-treated under 800℃, its infrared radiation ratiodeclines;Dravite heat-treated at 800℃ has the highest infrared radiation ratio, 0.90;andDravite's structure suffers from destruction above 900℃ heattreatment, so its infrared radiationratio goes down.
