Over the years, XTL has been offering customers high-quality products and efficient after-sales services with the aim of bringing unlimited benefits for them. Clay Crucible manufacturers If you are interested in our new product Clay Crucible manufacturers and others, welcome you to contact us.The product has good refractoriness under load capacity which is directly determined by the effective porosity and the volume density.
laboratory equipment high temperature fire assay crucible we manufactured are made with a scientific mix of high-quality materials and are carefully crafted. The clay crucibles have high mechanical strength and thermal shock resistance. It can usually be reused up to five times.
All our products are produced using fully automated equipment ensuring the consistent delivery of high- quality products.
Drill core samples (or others) are received at the laboratory, crushed, milled and dried in the oven. Samples are then separated into bags, tagged and weighed.
Next, the samples are prepared for the fusion process, which requires a reducing environment and so the samples are mixed with flux, a carbon source (coal dust) and litharge (PbO).
The samples are then placed into a fusion/ refractory crucible, ready to go into the furnace. The high tempareture (1000 – 1200°C) melts the sample while the flux fuses with the gangue (non-precious material) and the now liquid lead collects all the precious metals. The newly-formed Pb-Au-Ag-PGE concoction migrates to the bottom of the crucible due to its high density.
As cooled lead sample is then separated from the glass waste (slag) with a hammer, and placed in a porous bone ash (MgO) crucible, ready for the cupellation step.
The sample is then placed in a muffle furnace at around 1000°C. The lead oxidises with the aid of the inflowing air from the furnace muffle and then immediately melts and is absorbed into the crucible, leaving behind what is known as a precious metal prill.
The prill is then analysed for its precious metal content through dissolving it in aqua regia (a mixture of hydrochloric and nitric acid) and the concentrations determined by spectroscopic methods (AAS, ICPAES, ICPMS).
Eventual detection limits are in the region of parts per billion but accuracy is usually in the region of 3 -5% for this metallurgical analytical technique.
