Aluminium - Bauxite and Alumina

For Phoenix Fusion Machines

For a sample containing Alumina 60%-30%, Silica 40-50%.

Prepare a mixture containing the following:

XRFS LT100 8.0g
Lithium Carbonate 1.0g
Sample 1.8g

On all Phoenix fusion machines, use the following program

Premelt 900°C 180 seconds
Melting, without swirling 225 seconds
Melting, with swirling 165 seconds
Cooling 300 seconds

For determination of light and minors elements 

Flux types: XRFS65 HP. XRFSATLHP if fusion temperature is above 1200°C and provided the sample does not contain a high amount of alumina and silica.
