Top Reasons Behind the Increase in Export of Cenosphere from India?

A cenosphere is a lightweight, inert, hollow sphere which is made largely of silica and alumina filled with air and inert gas. Typically, cenosphere India is produced as a byproduct of coal combustion at thermal power plants. Usually, the color of this byproduct varies from gray to almost white, having a density of about 0.4 to 0.8 g/cm3 which gives them a great buoyancy. Combustion is a high-temperature exothermic redox chemical reaction of a fuel and an oxidant, generally, atmospheric oxygen producing oxidized in a mixture of a chemical reaction is termed as smoke. Burning in a fire producing flame, the heat produced can make combustion self-sustaining. This often goes through a complicated sequence of elementary radical reactions. That is solid fuels including wood primarily undergo endothermic pyrolysis to produce gaseous fuels where combustion is supplied to produce more heat.


The particles of Cenosphere India are hard, rigid, innoxious, lightweight, waterproof, and insulative making them highly useful for a range of products, notably as fillers. Filler particles are mixed with materials such as composite material, plastics, and concrete to lower the consumption and improve some properties of the mixture. Globally more than 555 million tons of fillers are used annually for different applications including paper, paint and coatings, plastics, rubbers, concrete, adhesives, and sealants.  Cenospheres are also used widely as fillers in cement for producing low-density concrete. In recent years, manufacturers also started using cenospheres for filling metals and polymers to make them lightweight composite materials with enhanced strength than other types of foam materials. These composite materials are known as syntactic foam. Aluminum-based syntactic foams are widely used in the automotive sectors.

The combustion at thermal power plant takes place at the temperature of 1500o to 1750o C (2730o to 3180o F) through complicated physical and chemical transformation. However, the chemical composition and structure of Cenosphere India considerably depends on the composition of coal then generated. Basically, the ceramic particles produced in fly ash have three type of structure:

  • Precipitator (solid)
  • Cenospheres (hollow)
  • Plerospheres (hollow with large diameter)

Properties and Components of Cenospheres

A cenosphere is a lightweight, hollow sphere made largely of silica and alumina and filled with air, metals, or gas. The Cenospheres are manufactured as a byproduct of coal combustion at thermal power plants. Cenosphere-based compounds were fabricated and categorized for their structural and mechanical properties such as tensile, flexural, impact and vibrant mechanical properties such as storage and loss moduli as a function of temperature. The structural qualities were characterized by Scanning Electron Microscopy (SEM) and Wide-Angle X-ray Diffraction (WAXD) though the thermal characterizations were prepared by conducting Differential Scanning Calorimetric (DSC) and Thermo-Gravimetric Analysis (TGA). The DSC studies revealed that increase in cenosphere content has resulted in a decrease in crystallinity of the composites.


The amount of separation in retrieving the Cenospheres from coal fly ash has been valued for both wet and dry separation processes through applying the terminal velocity concept of particles. The diameter and density of the particle are determined by sieving industrial cenospheres and coal fly as type IV. Depending on the estimation, the dry separation process executed similarly to the wet separation process, with a most favorable Newton’s efficiency of 0.54, just slightly lower than that of the wet separation process of 0.6.

The mortar cubes can be made with a combination of Cenospheres and silica fume as a standby for the cement. The test on mortar cubes shown that cement loses its strength because of the replacement of cenosphere, but the loss can be calm down by adding silica fume to it. The strength decrement decreases by ages, displaying that the strength attainment is reduced by the addition of cenosphere. The microstructure has also been studied to show the disintegrated structure on advanced replacement of cenosphere. It was also noted that the hydration products react with cenospheres and, due to this; decline in the quantity of portlandite was witnessed resulting in strength decrement.

Some Basic General Information about the Cenosphere from India

Cenospheres are light weight, inert hollow sphere comprising largely of silica & alumina and filled with air or inert gas. Cenosphere from India is naturally produced by the burning process of crushed coal-fired boilers. They are molded during the molten state of ash and reach spherical shape to have minimum surface. Inert gasses flowing along the burning gas stream also get locked inside the spheres. The bubbles caused by the inert gas combustion get into multiple forms with the frozen particles or in a concentric form, whose diameter is near the diameter of the particles.


The bubbles are found moving on the surface of fly ash. Cenosphere from India is unique free flowing powders composed of hollow, hard-shelled, and minute spheres. Cenospheres are formed from a small portion of the Pulverized Fuel Ash (PFA) which is produced from the burning of the coal in power stations. These are made up of iron, silica, and alumina. Generally, the size of the cenosphere particles ranges from 1 to 500 microns with an average compressive strength of above 3000 psi having a color variation from white to dark gray.
