Abstract
An oven system for the continuous firing of bindered ceramic materials includes a conveyer, a burnout section, and an oven section. The burnout section burns binder out of the ceramic materials without substantial firing of the ceramic materials. The oven section fires the ceramic materials at a temperature of 800.degree. C. to 1600.degree. C. in an oxygen atmosphere. The oxygen in the oven is at a pressure of at least one-half atmosphere, so that the ceramic products are at least substantially in the oxide form and have a density of at least 98% of the theoretical density. The oven has a wedge shaped door which interacts with a wedge shaped cavity to seal the door.
