What is Lead Used for

Lead is a highly toxic metal found in small amounts in the earth’s crust. Because of its abundance, low cost, and physical properties, lead and lead compounds have been used in a wide variety of products including paint, ceramics, pipes, solders, gasoline, batteries, and cosmetics. Lead may cause a range of health effects, from behavioral problems and learning disabilities, to seizures and death. Chronic lead exposure in adults can result in increased blood pressure, decreased fertility, cataracts, nerve disorders, muscle and joint pain, and memory or concentration problems.

Metallic lead has a bluish-white color after being freshly cut, but it soon tarnishes to a dull grayish color when exposed to air. These include hyperactivity; deficits in fine motor function, hand-eye coordination, and reaction time; and lowered performance on intelligence tests.

Lead is used in building construction, lead-acid batteries, bullets and shots, weights, as part of solders, pewters, fusible alloys and as a radiation shield.

Its four stable isotopes have 82 protons, a magic number in the nuclear shell model of atomic nuclei. Lead has a shiny chrome-silver luster when it is melted into a liquid.

Lead is bright and silvery when freshly cut but the surface rapidly tarnishes in air to produce the commonly observed dull luster normally associated with lead. It is a dense, ductile, very soft, highly malleable, bluish-white metal that has poor electrical conductivity when compared to most other metals.

Cadmium sulfide, cadmium selenide, cadmium telluride photovoltaic cells used in the manufacture. There are several ways of cadmium from cadmium dust or residueto get the metal cadmium. Cadmium is generally recovered as a byproduct from zinc concentrates. Zinc-to-cadmium ratios in typical zinc ores range from 200:1 to 400:1. Sphalerite (ZnS), the most economically significant zinc mineral, commonly contains minor amounts of other elements; cadmium, which shares certain similar chemical properties with zinc, will often substitute for zinc in the sphalerite crystal lattice. The cadmium mineral, greenockite (CdS), is frequently associated with weathered sphalerites and wurtzites [(Zn, Fe)S], but usually at microscopic levels.
Cadmium telluride thin-film photovoltaics are an alternative to the traditional silicon-based solar cells and are a preferred photovoltaic technology for commercial rooftop applications and for large-scale, ground-mounted utility systems.
Cadmium is clearly toxic to animals, and during the past few decades has become familiar to the public mainly due to its undesirable presence in fertilizers and elsewhere, rather than for its positive industrial applications. Metallic cadmium is rarely used industrially in pure form. Cadmium is mainly used for steel, iron, copper, brass and other metal plating, corrosion of alkaline substances and strong.

Mining products for Sale

Mining is the extraction of valuable minerals or other geological materials from the earth, from an ore body, vein or (coal) seam. The term also includes the removal of soil. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash. Mining in a wider sense comprises extraction of any non-renewable resource (e.g., petroleum, natural gas, or even water). Any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory, is usually mined.

Waht is Cadmium Telluride Targets

Cadmium telluride (CdTe) is a crystalline compound formed from cadmium and tellurium. It is used as an infrared optical window and a solar cell material. It is sandwiched with cadmium sulfide to form a p-n junction photovoltaic solar cell. Size: 100 * 100 * 6 Typically, CdTe cells use a n-i-p structure.

Cadmium Telluride Targets is used as an infrared optical material for optical windows and lenses but it has small application and is limited by its toxicity such that few optical houses will consider working with it. An early form of CdTe for IR use was marketed under the trademarked name of Irtran-6 but this is obsolete. It is also used to make thin film solar cells, accounting for about 6% of all solar cells. The properties that make CdTe superior for the realization of high performance gamma- and x-ray detectors are high atomic number, large bandgap and high electron mobility ~1100 cm2/V·s, which result in high intrinsic μτ (mobility-lifetime) product and therefore high degree of charge collection and excellent spectral resolution. Specifically, production could be expanded by a factor of 1000 to 10000 (estimates vary) before running out of Te.[
