Fire assay it' s a classical analytical method for applying metallurgical principles and techniques to analytical chemistry. To test the content of precious metals in minerals and metal products determined by melting and roasting. The method has the advantages of good sample representation, wide applicability, good enrichment effect and so on.
Working Temperature：≤1350℃（Fire assay working temperature less than 1150 degree ）
High refractoriness, no cracking
good corrosion resistance,
good thermal shock resistance,
no hanging residue, impermeable,
Ordinary series can use 2-3 times, the export
series can use 3-5 times, it's the for fire assay
Supply kinds of fire assay crucibles
Normal model and export level can be choose
Customize was acceptable
