High performance, multi-use Fire Assay Crucibles SH40, 40g (for an ore sample of 40g).
Upper diameter: 90mm
Inferior Diameter: 59mm
Our universal fire assay crucibles SH40, 40g ore sample, material of construction is fire clay mixed with other refractory materials. They withstand temperatures up to 1300`C.
This composition and their design give them an excellent resistance against flux attack, erosion, cracking and thermal shock. They can therefore work under harsh conditions, and have a longer life. Furthermore, they have a high resistance to thermal shock, and produce a faster fusion, and constant melting speed .
Another important feature of our fire assay crucibles, is that they are very stable because of their wide base. This is particularly relevant for furnaces that have an irregular ground due to flux attack and erosion.
Last but not least, their dense body also minimizes absorption losses.
