A fluidized bed for treating of product at high temperatures (1100 DEG C. to 1300 DEG C.) is possible, while overcoming problems such as slow start up times and contamination due to combustion gas. The fluidized bed uses an inert gas introduced to the bed to cause fluidization of refractory particles. Exposed surfaces or boundary layers of the bed are heated by infrared radiation produced exterior to the bed and absorbed by exposed particles of the bed. The thermal characteristics of the bed insure rapid dissipation of the absorbed energy. Electrically powered lamps produce the radiation and preferably are high intensity shortwave infrared radiation lamps. The lamps remain out of direct contact with the bed preferrably separated by a quartz wall or screen.
