The nitridation was carried out under a pressure of 0.1 Torr and with a flow rate of 100 sccm of ultra-high purity N2 for 10 minutes. The degree of nitridation and the nitrogen incorporation mechanism were evaluated as a function of the RPS power (0.5, 1.0 and 1.5 kW) and the dielectric temperature (300, 400 and 500 °C).
sintered under vacuum, argon, nitrogen, nitrogen/hydrogen gas mixtures. Only pure nitrogen is an active sintering atmosphere for aluminium, because it promotes shrinkage and sintered mechanical properties, as proved by bend test. A key feature in the use of nitrogen is the formation of aluminium (oxy)-nitrides.
The dependence of structure and phase formation of the combustion products on the terms of the process (high pressure of gaseous nitrogen, up to 100 MPa, combustion at condensed SHS, crystallization from melts) is considered for the systems of silicon-nitrogen, aluminum-nitrogen, and in complicated green mixtures for synthesizing SiAlONs.
The samples were dried in an oven at 80 oC overnight. The samples were grinded into fine powder after drying using a ceramic mortar and pestle. Accurately 2.0g of each of the powdered samples were weighed in a porcelain crucible. The fine powdered samples in the crucibles were ignited in a muffle furnace at 600 for three (3) hours.

Considerations in Heat Treatment - Heat Treat Doctor. Argon Ar An inert gas Carbon Dioxide CO Vacuum The absence of an atmosphere FEATURE | Industrial Gases/Combustion A key heat-treat consideration is the creation of an atmosphere within the furnace that is neutral to the parts being processed.
A 1½-inch-thick ceramic hearth plate serves as the work surface while protecting the ﬂoor insulation. Mott Corp. will use the furnace to dry castablebrick material in a nitrogen atmosphere. This furnace is sealed with a double-pivot horizontal swing door that keeps the hot face away from the operator.
verify that this atmosphere is present. The importance of furnace atmospheres Several types of atmosphere are commonly used in high tem-perature furnaces. They include exothermic and endothermic generated atmospheres, dissocia-ted ammonia, and nitrogen-based systems enriched with either hydrogen or dissociated methanol (CH 3 OH). If the

The selected baseline power system cycle concept integrates pressurized SOFC generator modules with a gas turbine and a steam turbine bottoming cycle. To maximize the system electric efficiency, a high degree of subsystem heat integration is employed. CO2 separation from syngas is accomplished prior to utilization by power generation components.
The annealing operation may be done in an atmosphere furnace or a vacuum furnace. The former may be of batch or continuous type. The furnace construction is similar to that given in Chapter 6, which deals with sintering technology. Annealing temperatures are kept as low as possible to minimize sintering. 4.2 Powder Mixing
Apr 08, 2002 · The removable atmosphere muffle (RAM) furnace provides increased versatility in heat treating and cooling under protective atmosphere. It uses a cart-mounted portable retort, which can be easily rolled in and out of the furnace chamber.
