摘要：

A weight loss rate-controlled organic extraction furnace was built and demonstrated using a multilayer green ceramic. Multirate weight loss schedules as well as automated atmosphere control and detection were demonstrated. The low thermal mass furnace showed good tracking with 300 degrees C heating and cooling rates. This furnace, coupled with appropriate PID control constants, facilitated feedback control which could extract organics rapidly without self-ignition to uncontrolled combustion. Controlled organic burnout was demonstrated at weight loss rates up to 0.5%/min in air. Damage-free multilayers were observed using a burnout rate requiring 150 min for extraction, rather than the days commonly associated with this task when using conventional furnaces.
