X-RAY FLUORESCENCE ANALYSIS EQUIPMENT (XRF)<br />
X-RAY FLUORESCENCE ANALYSIS EQUIPMENT (XRF)<br />
In many industrial <strong>laboratory</strong> applications XRF is used to identify the constituent<br />
components in the field of receiving inspection and quality <strong>as</strong>surance.<br />
In this context, homogenous melts produced under reproducible conditions provide<br />
the best starting b<strong>as</strong>is. Melts are far superior towhat are known <strong>as</strong> powder compacts<br />
in terms of me<strong>as</strong>urement accuracy and reproducibility.<br />
Anumber of manufacturers offer melt and fusion <strong>equipment</strong> in avariety of designs.<br />
All of them have one thing in common: special-purpose crucibles are needed for the<br />
melt and c<strong>as</strong>ting dishes made of platinum gold to produce the fused gl<strong>as</strong>s disk.<br />
Ögussa offers crucibles and c<strong>as</strong>ting dishes for the most common melting <strong>equipment</strong>.<br />
Custom fabrications are possible.<br />
The material which h<strong>as</strong> <strong>as</strong>serted itself is an alloy made of platinum with 5%gold<br />
because its greater stability at temperatures upto 1,200 °C (2192°F) ishighly suitable<br />
and exhibits less wetting especially with silicon melts which means that the melts can<br />
be more e<strong>as</strong>ily removed from the c<strong>as</strong>ting dishes.<br />
For applications at higher temperatures of up to max. 1,500 °C (2732°F) our fine-grain<br />
stabilized FKS Pt/Au 95/5 isespecially recommendable (see the table on page 23 –<br />
recommended temperature ranges).<br />
