A converter for an optoelectronic component, an optoelectronic component, a method for forming a converter for an optoelectronic component and a material for a reflector of an optoelectronic component are disclosed. In an embodiment, a converter includes a conversion element for converting a wavelength of electromagnetic radiation which passes through at least a part of the conversion element and a reflector, wherein the reflector includes a reflector material which includes MgFand/or an inorganic material as a matrix material in which a plurality of particles is embedded, wherein a refractive index of the matrix material amounts to at least 1 and at most 2, and wherein a refractive index of the particles amounts to at least 1.5.

Various embodiments may relate to a wavelength conversion element including at least one sintered wavelength converting material, wherein a grid is formed by channels within the sintered wavelength converting material, the channels are at least partially surrounded by the sintered wavelength converting material, the channels reach at least partially through the sintered wavelength converting material in a direction perpendicular or oblique to a main extension direction of the wavelength conversion element, and the channels contain a non-converting sintered separator material.

An opaque zone in the polycrystalline (PCA) discharge vessel of a high intensity discharge lamp may be made by creating residual pores in predetermined regions of the final-sintered discharge vessel. The control over the placement of the opaque zone is achieved by forming a carbonaceous residue in a specific region of the discharge vessel prior to final sintering. During sintering, the carbonaceous material causes residual porosity in the sintered PCA. The higher emissivity of the opaque PCA provides localized cooling in order to provide more control over the condensate behavior in the discharge vessel.

A method of forming hollow bodies of ceramic material suitable for use as the discharge vessels of high intensity discharge lamps includes forming a fugitive core of substantially pure graphite having a configuration matching the interior configuration of the hollow body. A flowable powder, including binders, of the ceramic material is formed and added to fill the annular space between a flexible elastomeric mold defining the outer contour and the fugitive core defining the inner contour. The ceramic powder is isostatically compressed in the mold about the core to form a sub-assembly. The sub-assembly is removed from the mold, heated at a rate and time and in a suitable atmosphere to volatilize the fugitive core, and subsequently the sub-assembly is sintered to form the hollow body.
