Lead Sulfide an overview ScienceDirect Topics

Lead sulfide has been reported to be an important direct narrow-gap semiconductor material with an energy band gap of −0.4 eV at 300K and a relatively large excitation Bohr radius of 18 nm. These properties also make lead sulfide suitable for infrared (IR) detection applications (Gadenne et al., 1989). These findings offer reasonable

Blast furnace Process engineering and chemistry,

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (coke), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with
