Abstract: Sintered bodies containing zirconia-based ceramic materials and partially sintered bodies that are intermediates in the preparation of the sintered bodies are described. The zirconia-based ceramic material is doped with lanthanum and yttrium. The grain size of the zirconia-based ceramic material can be controlled by the addition of lanthanum. The crystalline phase of the zirconia-based ceramic material can be influenced by the addition of yttrium.

Abstract: An additively manufactured dental crown with a wall having a bottom edge and an occlusal portion joined with the wall opposite the bottom edge. The wall and occlusal portion form an interior surface and an opposing exterior surface. By using additive manufacturing and materials for such, the dental crown can have thin walls with a thickness of less than 300 microns at the thinnest portion of it and can include fine printed features such as identifiers, internal ribs, slots, porous meshes, and retention elements.

Abstract: A microwave furnace has a furnace chamber formed between a chamber housing and a sintering platform for an object to be sintered. A microwave source is arranged for emitting microwaves into the furnace chamber. The microwave furnace further has a susceptor that comprises a material which over a temperature range of the material of at least 23 C to 700 C couples into microwaves. The susceptor and the furnace chamber are movable relative to each other between a first position, in which the susceptor is positioned relative to the furnace chamber, and a second position in which the susceptor is positioned further retracted from the furnace chamber relative to the first position. The invention helps providing a zirconia material with a relative homogeneous material structure.
