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 with 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 the weight of formulated products.

CENOSPHERE - HOLLOW CERAMIC MICROSPHERES (EXPANDED MINERAL MATERIAL CONTAINING ALUMINA AND SILICA)

A hollow microscopic ball made up of some minor ceramic elements with smooth silica-aluminum is Cenosphere (Expanded Mineral Materials Containing Alumina and Silica). Its derivation has been done from the extreme fire of coal-fired power plants and now it is being used to improvise the qualities of manufactured products in India.

In India, Cenospheres (Expanded Mineral Material Containing Alumina and Silica) are made of iron, alumina & silica by Petra Buildcare Products. In thermal power plants, burning coal produces fly ash which has ceramic particles largely made of alumina and silica.

The size range of cenospheres varies from 1 to 500 microns with 3000+ psi average compressive strength. In low-density concrete, Cenosphere can be used as fillers; It can also be used in plastics and composite materials such as kayaks, surfboards, bowling balls and for automotive components it can be used in floor tiles, fire bricks, and other industrial materials.

Cenospheres (Expanded Mineral Materials Containing Alumina and Silica) are Hollow ceramic microspheres that are a by-product of coal burning power plants. When pulverized coal is burned at power plants fly ash is produced. Cenospheres are the lighter particles that are contained within the fly ash.

Most cenospheres are "harvested" or scooped up from ash ponds. Ash ponds are the final resting place for fly ash when wet disposal is carried out. Some cenospheres are also collected at the power plants themselves. The wet microspheres are than dried, processed to specifications, and packaged to meet customer requirements.

Not all cenospheres are alike. In fact, they can be quite different. The properties of cenospheres depend on the consistency of the coal used and the operating parameters of the power plant. As long as these two factors remain constant, the cenospheres will be quite consistent.

Chemical Properties of Cenosphere
  • Sillica : 55% - 65%
  • Aluminia : 25% - 35%
  • Iron Oxide : 1% - 5%
  • Titania :0.5% - 1.5%

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 takes 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. If you are looking for Cenosphere manufacturers in Nagpur, Chennail and Kolkata, Petra Buildcare Products manufactures different types of cenosphere in India with various aspects.
