Pressed-sintered crucibles. It is in the Kyropoulos process that our pressed-sintered crucibles show their strengths to best effect. They are repeatedly heated to more than 2000°C (3632 °F) and then cooled down again. With our many years of experience in the field of powder metallurgy, we produce crucibles of a particularly high density and purity.
Pressed and Sintered Crucibles. Powder is pressed and sintered to final shape geometries to meet the requirements of each furnace design; Spin-Formed Crucibles. Large molybdenum plate blanks are hot spun formed to the specified product geometry; Elmet has experience in a wide variety of molybdenum crucible sizes up to 20″ diameter; Milled Crucibles

Pressed-sintered crucible is formed by sintering and hot isostatic pressing (HIP). Net size and surface are machined by further milling, turning and polishing. They are widely used in sintering furnace, synthetic sapphire growing furnace, rare earth and glass melting furnace and related equipments.
The powder is pressed and sintered to final shape, it is one of the most popular crucibles. * Spin-formed Crucibles Large molybdenum plate blanks are hot spun formed to the specified product geometry.
MOLYBDENUM PRESSED AND SINTERED BILLETS. Where highest purity, maximum toughness, and ductility at low temperatures are required, arc-cast molybdenum mill products are available in a special low-carbon grade. This material is % pure molybdenum and contains a maximum of .010% residual carbon, compared to the nominal .030% maximum carbon content of normal arc-cast molybdenum.
PLANSEE’s pressed-sintered crucibles are made from tungsten or molybdenum and have a surface roughness of below μm. when the crucible’s surface is rough, the sapphire cannot be easily extracted and this tends to damage the crystal. Besides, the crucible also gets damaged in the process.
The sapphire crystal growth methods KY and EFG readily serve for more than 85 % of the worlds sapphire quantity share. In both methods, the liquid alumina is placed in pressed-sintered crucibles, typically made of tungsten for the KY process and made of molybdenum for the EFG process.
Most of the molybdenum crucibles are sintered with pure molybdenum powders. The reason to use pure molybdenum powders is that they can prevent impurities from generating when other metals are melted in the crucible. Molybdenum crucibles have properties of high temperature resistance and low pollution.
MOLYBDENUM CRUCIBLES FOR SAPPHIRE CRYSTAL GROWTH (LED) IN HIGH TEMPERATURE FURNACES. These high temperature materials are characterized by their high thermal and electrical conductivity, low coefficient of thermal expansion, and excellent strength and stability at temperatures above 2,000°C. Customer specific furnace components and fixtures for high temperature furnaces are uniquely designed and are supplied by . Starck.
