Modern Microwave Methods in Solid

In these cases, a susceptor material is often used to raise the reaction temperature to a point where the dielectric properties are more favorable for the reactant. An example of this is in the MW heating of alumina which becomes 3000% more efficient when the

New Induction Heaters Products

In a recent test application set up for demonstration purposes, UltraFlex proved the energy- and cost- efficiency of induction heating for a steel cylinder, prior to using it for epoxy curing. The demo setup had been done per request of a plastics manufacturer looking to switch from resistance heating to induction heating, to reduce heating cycle times and achieve increased repeatability.

Fabrication of graphene

2014/6/30The HMA (Figure 1) combines this microwave heating with an additional heating from an effective microwave absorber (susceptor) 17,18. Upon microwave irradiation, the temperature of a susceptor (graphite in our case) increased dramatically first and the susceptor transfers the heat to the target material via the conventional heating mechanisms.

Microwaves (MW) have also been used to ignite CS [11], usually applying a hybrid heating method in which an external microwave susceptor was used to trigger the reaction. Microwave-activated combustion synthesis (MACS) of titanium aluminides belonging to the broad single-phase regions of TiAl and Ti 3 Al, respectively, was performed by Jokisaari et al. 1 The article is published in the original.

The substrate temperatures are achieved by localized susceptor heating. The gas control and purge sequences are all computer controlled, electronically interfaced and actuated by pneumatic valves. The multi channel configuration allows doping and performing complex compound reactions with 5 different chemical complexes in a single deposition process (SAS).
