영문 초록

Sintered Al₂TiO₅ has a very low thermal expansion and infrared radiative selectively emitting large amounts of far infrared rays. However, it is week in mechanical strength. Spectral infrared emittance, thermal expansion coefficient, and mechanical strength of Al₂TiO₅-clay composites were studied to develop a material for far infrared radiators. The composites containing 10~50 mass% Jungsan clay had high emittance in the range of 2,000~200cm-1. The bending strength of the Al₂TiO₅-clay composites increased with increasing clay content. The Al₂TiO₅-clay composites with a clay content of 50mass% and heat-treated at 1,200℃ had a large strength for infrared radiators ; 86MPa. The average linear thermal expansion coefficient from 200~1,000℃ of the 50mass% Jungsan clay containing composited heat-treated at 1,200℃ was lower than 3.87X10-6/℃.
