Cenosphere

Cenosphere (Expanded Mineral Materials Containing Alumina and Silica) are a by-product of coal burning power plants and are lightweight, inert, hollow sphere filled With air or inert gas. the colour of Cenosphere varies from grey to almost white and their density is about 0.4 – 0.8 g/cm3 (0.014 – 0.029 lb./cu in), which provides them with buoyancy.
Cenosphere behaves like tiny ball bearings to improve workability, flow under pressure, reduce shrinkage, enhance isotropic properties and reduce resin, binder or water demand due to their low oil absorption level and high packing factor. Physically, Cenosphere is hard, rigid, light, waterproof, innoxious, and insulative. By utilizing these characteristics of Cenosphere it is possible to produce materials witd excellent heat insulating properties. Cenosphere combine all the advantages of spherical shape with the additional benefits of low density at an economic cost. with low densities Cenosphere reduces tde weight of formulated products.

Characteristic of Cenosphere

We have developed Cenosphere of different qualities under our brand name LITEFILL. In current era, LITEFILL is the World's No. 1 light weight high performance filler material because of their low density, small size, spherical shape, mechanical strength, high melting temperature, chemical inertia, insulating properties and low porosity, finds a wide range of applications in industry. In particular they are ideal for reinforcing materials or imparting properties of resistance to corrosion, or thermal and sound insulation to coatings or paints. They can be described as multifunctional fillers and integrate well in resins and binders such as thermoplastics and thermosetting.” They help reduce product's cost and weight, improving multiple performances of the products.

Cenospheres Benefits

The spherical shape of Cenospheres improves flowability in most applications and provides a more even distribution of the filler material.
This cenosphere is highly used in oil drilling, paints, fillers industries etc. Our products are used in oil field cementing to decrease the slurry density.Like sphered products, the properties of these are same. Therefore, this is also known as Glass Beads, Hollow Ceramic Sphere or Microspheres owing to the unique combination of spherical shape, low specific gravity, controlled size, high compression.
Cenospheres primarily used to reduce the weight of Plastics, Rubbers, Resins, cements and extensively as filler lubricants in oil drilling operations under high heat and high stress conditions down the hole. Also used as oil well cementing, mud putty and similar applications.
Cenospheres were first used in the United states as an extender for plastic compounds , as they are compatible with plastisols thermoplastics, Latex.

How Cenosphere is Produced ?

The process of burning coal in thermal power plants produces fly ash containing ceramic particles made largely of alumina and silica in India. They are produced at temperatures of 1,500 to 1,750 °C (2,730 to 3,180 °F) through complicated chemical and physical transformation. Their chemical composition and structure varies considerably depending on the composition of coal that generated them.
The ceramic particles in fly ash have three types of structures. The first type of particles are solid and are called precipitator. The second type of particles are hollow and are called cenospheres. The third type of particles are called plerospheres, which are hollow particles of large diameter filled with smaller size precipitator and cenospheres manufacture in India.

Cenosphere Manufacturing:

Over the last 30 years, cenospheres and its definition have been completely changed. In the 1990s it was largely limited to the carbonaceous sphere. Oxygen-Deficient combustion is a reason of carbonaceous sphere which occurs because of liquid fuel droplet that has been cooled below 392 °F (200 °C) before consumption. An indication of fuel cenosphere combustion taken place using the open burning of heavy liquid fuels and fuel droplets such as a thermoplastic material or asphalt which causes bubbling as they get burned and the impact of the bursting of the bubbles has created airborne droplets of fuel.In environmental microscopy this is the basic definition that is used, to differentiate between high-temperature fly ash which is the result of efficient combustion of fuels with inorganic contaminants and inefficient combustion of liquid fuels. The color of fuel cenospheres will always be black.
As defined above the refractory cenosphere is synonymous with glass microspheres or microballons and excludes the traditional definition of fuel cenospheres. Instead of microballoons, name cenosphere has been widespread and became an additional definition of it.

Cenosphere - Global Demand Analysis

Cenosphere is free flowing and hollow ceramic sphere in coal fire thermal power plant during burning of the coal at high temperature. It is being used in various industries including oil & gas, building, plastics, automotive and more.
New application areas of cenosphere are always being researched upon. There are few factors that contributes chiefly to the increase demand of the cenosphere in industrial sector. As its role is to improve the durability and increase the strength of products along with allowing weight reduction and being cost effective. These factors enhances its application and demand as it interests governments, business and industrialist.
Cenosphere market is anticipated to grow strong for its increasing applications in different industries. New thermal power plants is one of the factor driving the increasing demand. It has been analysed that the growth of this segment is forecasted to its high demand in countries like Europe, North America, and Asia Pacific like India, China and Singapore. Due to rise in the production activities in Middle East countries and also increase in exploration of hale gas in North America, it is expected that the demand of cenosphere will increase over the years.
