Superior Resistance to Chemical Attack

Engineered from high-purity magnesium oxide, 9C Magnesia Cupels are highly resistant to aggressive reagents like lead oxide (PbO), ensuring minimal degradation during assaying. Their basic refractory nature provides reliable performance under demanding chemical conditions, extending lifespan and preserving consistency in laboratory work.

Minimized Shrinkage & Optimal Absorption

Through a meticulous pressed and sintered manufacturing process, these cupels achieve low shrinkage and precise dimensional stability, even at extreme temperatures. Their controlled open porosity maximizes the absorption of lead and litharge, enhancing the separation of precious metals during refining and assay procedures.

Engineered for Laboratory and Industrial Needs

The design incorporates a shallow, hemispherical profile, ideal for efficient metal separation in both gold and silver assay applications. With low thermal conductivity and strong structural integrity, the cupels support repeated heating cycles in all standard assay furnaces, providing reliable results for Indian and international laboratories.

FAQs of 9C Magnesia Cupels:

Q: How should 9C Magnesia Cupels be stored to maintain their quality?

A: 9C Magnesia Cupels should be kept in a cool, dry place to prevent hydration. Proper storage conditions help preserve their structural integrity and ensure a long shelf life.

Q: What benefits do these cupels offer during the metal separation process?

A: Their optimized absorption capacity and controlled porosity enable efficient uptake of lead and litharge, leading to precise separation of precious metals such as gold and silver in assaying and refining applications.

Q: Where can 9C Magnesia Cupels be used?

A: These cupels are suitable for laboratory metal analysis, gold and silver assaying, and refining operations. They are compatible with all standard assay furnaces used in laboratories and industrial settings.

Q: What is the manufacturing process used for 9C Magnesia Cupels?

A: The cupels are produced by pressing and sintering high-purity MgO powder. This process yields minimal shrinkage during firing and ensures a fine-grained, smooth surface with reliable dimensional stability at high temperatures.

Q: When should 9C Magnesia Cupels be replaced during routine use?

A: Cupels should be replaced after each assay cycle or when significant absorption or physical changes are observed. Their high strength and refractory properties allow for repeated use, but periodic inspection ensures reliability and accuracy.

Q: How do 9C Magnesia Cupels withstand extreme heat and chemical exposure?

A: With a refractoriness under load exceeding 1500C, over 98% MgO content, and high resistance to PbO, these cupels maintain their structure under stressful thermal and chemical environments encountered during assaying.

Q: What makes 9C Magnesia Cupels advantageous over other types?

A: Their high purity, dimensional stability, minimal shrinkage, and efficient absorption characteristics ensure accurate results, durability, and cost-effectiveness, making them the preferred choice for precious metal assay professionals.
