Product Description
Manufacturer wholesale Factory Price Hot-selling Metal Pb lead pellets- Lead Granules CAS 7439-92-1 Radiation Shielding Material
Explain:
1.Lead-acid battery manufacturing: Lead granules are the primary components of the positive and negative plates in lead-acid batteries, used for storing and releasing electric energy.
2.lead has a relatively low melting point, which makes it easy to cast and shape, reducing production costs and complexity. Furthermore, lead's ductility and corrosion resistance ensure that lead pellets remain stable in various environments, extending the lifespan of products. However, it's important to note that the use of lead requires careful handling due to its potential environmental and health hazards.
3. The melting point of lead (Pb) is approximately 327.502°C (621.504°F or 600.652 K), its boiling point is around 1740°C (3164°F or 2013 K), it has a relatively low hardness, ranking around 1.5 on the Mohs scale, and it is not soluble in water. In English: The melting point of lead (Pb) is approximately 327.502°C, its boiling point is around 1740°C, it has a hardness of about 1.5 on the Mohs scale, and it is insoluble in water.
Properties:
Pb, or lead, is a heavy, bluish-gray metal that is soft and malleable. Its properties include a high density of 11.34 grams per cubic centimeter, a melting point of 327.5 degrees Celsius, and a boiling point of 1749 degrees Celsius. Lead is a poor conductor of electricity but conducts heat well. It has a characteristic crystal structure known as face-centered cubic (FCC) at room temperature. Lead is highly resistant to corrosion and can form a protective oxide layer when exposed to air. Its ability to absorb radiation makes it useful in shielding applications. However, lead is toxic to humans and the environment, affecting multiple organ systems and causing serious health issues, especially in children. Lead particles, due to their small size, can be particularly hazardous as they can be inhaled or ingested more easily. In terms of its use, lead has been historically important in batteries, ammunition, radiation shielding, and as a pigment in paints, although its use in such applications is now being phased out due to health and environmental concerns. Lead's atomic number is 82, and it is located in the carbon group (Group 14) of the periodic table. Its chemical reactivity is relatively low, and it forms stable compounds with many elements, such as lead(II) oxide (PbO) and lead(IV) oxide (PbO2). Despite its toxicity, lead's unique properties make it an important material in various industrial applications, albeit with strict regulations and safety measures in place to minimize exposure.
Storage conditions:
Tungsten powder shall be stored in a dry, cool and sealed environment and shall not be exposed to the air. In addition, heavy pressure shall be avoided and it shall be transported as ordinary goods.

Applications
Pb, or lead particles, have various applications including use in batteries, particularly in lead-acid batteries which are widely used in cars and other vehicles for starting, lighting, and ignition. They are also employed in radiation shielding, such as in protective barriers for X-ray and CT scan rooms, and in weights and balancing components due to their high density. In addition, lead particles can be used in ammunition, although there is a trend towards non-toxic alternatives due to environmental and health concerns. Furthermore, they have historical and artistic applications in stained glass, although this use is declining due to toxicity issues. Lastly, lead has been used in plumbing and construction, but these uses are also diminishing due to the discovery of lead's harmful effects on health.
Storage conditions
This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.
