Product Introduction


How to make Mineral analysis ceramic crucible

1. There are two types of forming methods for clay crucibles: roll forming and stamping forming.

2. Physical and chemical indexes of clay crucible: refractory temperature 1580℃, alumina content: between 40% and 45%

3. Features: High refractoriness, no slagging, no penetration, no cracking, it is the first-class auxiliary consumable for fire Assay.

All raw materials are ball milled, blended, and filtered in proportion.

Put the practiced mud in a mud press, press it into a circle, and cut.

Customize corresponding molds according to different size specifications

Put the cut mud into the mold and rotate it at high speed to form a blank.

Place the formed crucible on a drying cart to dry, and put it in a high-temperature kiln for 11 hours.

Wrap up and store.

Manufacturing with the latest automated technology offers guaranteed sizing consistency which is critical with multi-pour systems and automated lines. Meanwhile, carefully selected raw materials and more reasonable formulation with low caustic soda, low iron content and high silicon content enable Yosion crucibles to ensure high temperature resistance up to 1500°C.

Customized sizes and services are available.

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.
