Abstract

Se presenta un horno microondas para calcinar material cerámico bajo presión que comprende un contenedor (2), un cuerpo en forma de caja (13) hecho de alúmina de baja densidad y que gira dentro del contenedor (2) alrededor de un eje geométrico vertical, una cámara de calcinación para el material cerámico, que consta de la cavidad interna (14) del cuerpo con forma de caja (13), un magnetrón (28) para la generación de microondas y una guía de ondas (27) para introducir las ondas dentro del contenedor (2) a través de una abertura (24), medios diseñados para generar una presión mayor que la presión atmosférica dentro del contenedor (2). El magnetrón (28) y la guía de ondas (27) pueden moverse a lo largo de la abertura (24) para producir un campo electromagnético básicamente uniforme dentro del contenedor (2); elementos (15) hechos de material con un alto factor de pérdida dieléctrica se disponen al lado de las paredes de la cavidad interna (14) del cuerpo con forma de caja (13).
