Lead
oxide, a range of products that is formed by the oxidation of Lead
in the forms of liquid and solid. Lead oxides are basically an
oxide’s family varying in colour (grey/green, red, and yellow), in
degree of oxidation (PbO, Pb3O4, PbO2) and in crystal structure (in
forms of PbO, orthogonal and tetragonal). Lead oxide is a term that
can be either Lead monoxide or litharge Lead tetroxide or Red Lead
or Gray or Black oxide which is a mixture of 30 percent metallic
Lead and 70 percent Lead monoxide. Black Lead is made for specific
use in Lead acid storage batteries manufacturing. Due to large use
in the Lead acid battery industry, Lead monoxide is one of the most
important compounds of Lead, based on volume. Due to its electrical
and electronic properties, litharge is also used in various
components for different types of use like capacitors, electro
photographic plates, and Video tubes, even in ferromagnetic and
ferroelectric materials. Their wide range of chemical and physical
properties, Lead oxides have been know and used worldwide since
before the ancient Romans.
Turn-key solution for Lead Oxide Manufacturing
We provide Turn-key solution for Lead Oxide Manufacturing.
The followings are the main applications for Lead oxides in current
use:
Lead oxide in batteries: This is the most dominant
application for Lead oxide. Oxide for battery applications can be
further classified into three major types of battery.
SLI (starting, lighting, and ignition): Every vehicle that
having a Lead-acid battery uses 5-10 kg of Lead oxide in its
production. This represents a vast uses of Lead oxide on a worldwide
basis.
Traction
batteries: These types of batteries are designed for multiple
charge-discharge cycles and tend to use red Lead (Pb3O4) oxide in
their production. These are used to power all manner of electrical
vehicles like fork lift trucks, golf carts, milk floats, etc.
Stationary batteries: These are batteries required for
stand-by power applications in case of mains supply failure in
hospitals, computer installations, telecoms networks, etc. Again,
red Lead (Pb3O4) oxide is common in these units.
“Most of the Lead used in batteries is recycled through an effective
collection and recycling network. The vast amount of this Lead is
refined and returned to the battery production process.”
Lead oxide as pigments: The major Lead pigment is red Lead
(Pb3O4), which is used principally in ferrous metal protective
paints Litharge -a bright yellow form of Lead monoxide still finds
applications in the production of yellow pigments.
Lead oxide in glass: Leaded glass crystal can contain 24-28%
of Lead oxide which enhances clarity and density. The overall
average of television tube contains 5- 8 kg of Lead oxide to absorb
harmful radiation. Optical fibers also rely on Lead oxide to enhance
the refractive index. Lead oxides are also used in special optical
glasses, x-ray protection glasses, etc.
Lead oxide in ceramics: Lead oxides have been used in glazes
and enamels since antiquity. Lead oxide enhances the thermal, colour
and wears properties of such coatings.
Lead oxide in PVC: Lead oxide is used as Lead stabilisers in
PVC processing. The Lead stabilisers improve the thermal stability
of PVC, allowing high temperature processing as well as improving
the electrical and UV resistance properties. Common PVC applications
are in window profiles, cable sheathing, pipe work, and ducting.
It also has important markets in the production of many Lead
chemicals, dry colors, soaps.
