Granular Fluxes with Oxidizers
All fluxes are available with addition of various % of lithium nitrate. The oxidizing agent is embedded in the flux and will not separate during handling.
All fluxes are available with addition of various % of sodium nitrate. The oxidizing agent is embedded in the flux and will not separate during handling.
Additives
A fusion procedure relies on the dissolution of a properly oxidized sample in the molten flux. During the procedure, a sub-oxidized sample can be oxidized with a nitrate-based compound. When heated, such oxidizer will promote the full oxidation of your sample in order to ensure a complete dissolution in the flux.
The non-wetting (nwa) agents will avoid the melt sticking on both the crucibles and the molds. Too little nwa could result in dirty crucibles and cracked beads.
Our fluxes are available with the additives integrated at the factory. But for method development, an inventory of various additives are convenient tools in any fusion lab.
