- A cenosphere is a
lightweight, inert, hollow sphere filled with inert air or gas,
typically produced as a byproduct of coal combustion at
thermal
power plants.
- A cenosphere (ceramic
sphere) is a hollow microscopic ball made of smooth silica-aluminum and
other minor ceramic elements.
- Cenospheres, derived from
the inferno of coal-fired power plants, have been used for more than 30
years to improve the qualities of
many manufactured products.
- Cenospheres are hard and
rigid, light, waterproof, innoxious, and insulative. This makes them
highly useful in a variety of products,
notably fillers.
- Cenospheres are now used as
fillers in cement to produce low density concrete.
- The process of burning coal
in thermal power plants produces fly ash containing ceramic particles
made largely of alumina and silica.
These particles form a part of
the fly ash produced in the burning process.
- Cenospheres are unique free
flowing powders composed of hard shelled, hollow, minute spheres.
- A small proportion of the
pulverised fuel ash (PFA) produced from the combustion of coal in power
stations is formed as
Cenospheres.
- Cenospheres are made up of
silica, iron and alumina.
- Cenospheres have a size
range from 1 to 500 microns with an average compressive strength of
3000+ psi.
- Colors range from white to
dark gray. They are also referred to as microspheres, hollow spheres,
hollow ceramic microspheres, microballoons, or glass beads.
- Cenospheres are essentially
thin-walled glass spheres with a relative density of less than
1.0.
- Cenospheres occur in minute
concentrations; a ton of South African fly ash gives rise to only one kg
of cenospheres.
- After recovery, drying and
size classification, cenospheres produce a free flowing white or
greywhite powder.
- Cenospheres, also referred
to as hollow ceramic microspheres, is a non-porous, inert, hollow,
alumina-silicate, micro balls that is formed by burning of pulverized
coal during power generation process.
- Cenospheres are formed from
coal combustion ash when it is in a molten state.
- Cenospheres are used as
fillers in lowdensity concrete; in plastics and composite materials used
for manufacturing bowling balls, kayaks, surfboards, and automotive
components; and in fire bricks, floor tiles, and insulating
materials.
- They are used to replace
minerals and resins where the benefits may be as diverse as weight
reduction, improved insulation, reduced shrinkage, improved fire
resistance reduced friction, improved surface finish or simply easier
application.
- Float-sink with
centrifugation analyses using distilled water and lithium metatungstate
solutions were used to quantify the recovery of Cenospheres of various
densities.
- Cenospheres are incorporated
in polymeric materials to obtain composites of low density and high
compressive strength, known as syntactic foams.
- Didcot Power Station is able
to harvest the Cenospheres from the lake at Radley and approximately 400
tonnes are made available each year.
- The grade of a Cenospheres
most often used for high quality and smooth coatings is more like fine
dust and not granular like sand.
- The Cenospheres are produced
only by a highly filtered processing of the fly ash.
- Cenospheres are the key
ingredient in Ceramic coatings.
- Cenospheres are
derived “flyash” in a multi filtration process, then filtered again to
separate the specific grades and qualities of Cenospheres used in
coatings and high tech.
- Cenospheres is used in high
tech manufacturing, aerospace space and other technologies.
