The sintering furnace LT 02/13 CR is perfectly suited for sintering of cobalt-chromium restorations. The blanks are placed in a special sintering bell and will be heat-treated under argon. The specific design in combination with sintering pearls provides for good sintering results in a nearly oxygen-free atmosphere at very low argon consumption.
The slag and pure indium metal were held in magnesia crucible under CO-CO 2 atmosphere for equilibration. After equilibration, the samples were quickly extracted from the furnace and quenched by dipping the crucible into brine. The slag and metal samples were carefully separated from the crucible.
vacuum furnace. Dispelling notions for conventional cobalt-chrome alloy by a hardness of 260Hv0.5, technical operability is provided which is equivalent of that of gold-silver-palladium alloy with hardening treatment.
The metal can be isolated from tantalum, and prepared in several ways. It is a shiny, white, soft, and ductile metal, and takes on a bluish cast when exposed to air at room temperatures for a long time. The metal starts to oxidize in air at 200°C, and when processed at even moderate temperatures must be placed in a protective atmosphere.

Crypton sintering requires a reduced-oxygen atmosphere, which is. obtained by the use of argon. Argon is an inert gas in a compressed-gas cylinder
Cobalt-chrome disc with dental bridges and crowns manufactured using WorkNC Dental Cobalt-chrome or cobalt-chromium ( CoCr ) is a metal alloy of cobalt and chromium . Cobalt-chrome has a very high specific strength and is commonly used in gas turbines, dental implants, and orthopedic implants .
Porcelain fused to metal prosthesis has been one of the most widely used types of dental prostheses. It is Background and Objectives: This in vitro study seeks to evaluate and compare the marginal and internal fit of cobalt-chromium copings fabricated using the conventional and direct metal laser sintering (DMLS) techniques.

Abstract Introduction: In dental medicine, impressions can be the cause of cross-infection between the clinic and the laboratory.
Apr 22, 2014 · The increased worldwide interest in utilizing Co-Cr alloys for dental applications is related to their low cost and adequate physico-mechanical properties. Additionally, among base-metal alloys, Co-Cr alloys are used more frequently in many countries to replace Nickel-Chromium (Ni-Cr) alloys.

The feedstock was prepared by mechanically mixing iron ASC 100.29 powder with designated carbon powder for 30 minutes. Powder mass was compacted at 30°C and 150°C by applying simultaneous downward and upward load of 130 kN. The defect-free green compacts were sintered at argon gas fired sintering furnace at different sintering schedule.
