Once the froth is skimmed off and dried, it’s about 80% pure lead sulfide and ready for smelting. The Bunker Hill Mine used to have the largest lead smelter in the world, ...

Somobrata Acharya explores the history, properties and uses of lead — an ancient metal that is still very relevant to today's technologies, but should be used with caution.

Lead-icine Upper-class men and women in ancient Egypt commonly defined their eyes with kohl—a dark powder made from lead ...

Lead sulfide -- also known by its mineral name, galena -- is a naturally occurring mineral found in Missouri, other parts of the world, and now . . . other parts of the solar system.

Typically, lead sulfide is expected to form a cubic crystal structure, characterized by high symmetry similar to that of table salt. In this structure, ...

The Integrated Detector Assembly (IDA) lead selenide and lead sulfide high-sensitivity infrared detectors integrate their relevant electronics within a compact, hermetically sealed TO-8 package ...

Accordingly, lead sulfide quantum dots can absorb light over a wider range of frequencies. This means they can absorb a greater proportion of the light from the sun when compared to other smaller ...

In 1946, U.S. Navy physicist William B. McLean had a novel idea. He and his team had been toying around with lead-sulfide proximity fuzes that were sensitive to infrared radiation.

Typically, lead sulfide is expected to form a cubic crystal structure, characterized by high symmetry similar to that of table salt. In this structure, ...
