Roll to roll sintering system for wide inorganic tape material and sintered articles

A system, comprising:

• a continuous tape material comprising a green tape material, comprising powdered polycrystalline ceramic in an organic binder, and a backing layer;
• a spool on which is wound the continuous tape material comprising the green tape material and the backing layer;
• a take-up reel;
• a heating station comprising at least one furnace, the heating station configured to receive an unwound length of the continuous tape;
• the heating station comprising:
• a first curved section such that the continuous tape material is bent through a radius of curvature, the radius of curvature being in a range of 0.01 m to 13,000 m;
• and
• at least two rollers defining the first curved section over which the continuous tape material is bent,
• wherein the heating station is controlled to provide at least a portion of the heating station with an air free atmosphere.
