Lab analysis fire clay crucible

Introduction:

Our fire assay crucible is a high-performance refractory ceramic container specially designed for the fire assay
 process.It is mainly used for the separation, collection and determination of precious metals (such as gold, silver,
 platinum group metals) in high-temperature melting, oxidation, reduction and other processes. With excellent 
high-temperature resistance,thermal shock resistance and chemical stability, it can maintain structural integrity
 under multiple thermal cycles, ensuring the accuracy and efficiency of precious metal analysis experiments.
Applications
Our fire assay crucible is widely used in precious metal analysis and high-temperature melting scenarios, mainly
 including:

1:Quantitative analysis of precious metals such as gold, silver and platinum group elements

2:Fire assay process of mineral samples, including oxidation smelting, absorption, separation and other steps.

3:Laboratories in the metallurgical industry, used for inspection of gold mines, silver mines and alloy materials

4:Scientific research experiments, such as small-scale and pilot-scale high-temperature reactions in fire smelting

5:Precious metal refineries, used for the initial refining of gold and silver
