Know How Cenosphere is processed

The word Cenosphere is derived from two Greek words ‘Kenos’ which means hollow or void and ‘Sphaera’ which means sphere or round, that literally means ‘hollow spheres’. A Cenosphere is a type of hollow sphere, light weighted and inert that is made of silica and alumina. It is produced as a byproduct of coal combustion at thermal power plants. Cenosphere are light, hard and rigid, waterproof and insulative. It is excellent light-weight filler. This property of light weight makes them useful in a variety of products, especially in fillers. Nowadays, Cenosphere are used in cement as fillers to produce low density concrete. Now, some of the manufactures have started mixing Cenosphere with metals and polymers to make them light weight. In other words, Cenosphere is also known as Hollow Ceramic Microspheres. The density of Cenosphere is about 0.4-0.8 g/cm3 that is, 0.014–0.029 lb/cu in, this property gives them great lightness. Their color varies from gray to almost white.

Cenosphere are occurred naturally as a byproduct of the burning of coal in thermal power plants. The burning process of coal in thermal power plants produces fly ash of coal that contains ceramic particles that is made of Alumina and Silica. The process of coal burning and the fly ash is produced at temperatures of 1,500 to 1,750°C that is (2,730 to 3,180 °F). It is formed through complicated physical and chemical transformation. The chemical composition and structure depends upon the composition of coal that generated them.

Here are some of the uses of Cenosphere:

  • In synthetic foams, Cenosphere are used as filler. It gives us a number of benefits such as adding strength to foam, reducing costs, thermal protection etc.
  • For years, Cenosphere have been used in oil drilling. It is used to lower the density of a petroleum cement paste.
  • It is often used in paints and coating to regulate infra red radiation.
  • The properties of Cenosphere such as re-formable, strength etc don’t let the thermosetting and thermoplastics shrink. This is the reason that Cenosphere is being used for years in manufacturing polymers and plastics.

Properties of Cenosphere Available in India

Cenospheres are the sphere of inert hollow silicate. Cenospheres primarily utilized to abridge the weight of types of cements, Rubbers, Plastics, Resins, etc. utilized all-encompassing as filler lubricants in oil drilling procedure under eminent heat and eminent stress conditions down the hole. Also utilized as oil well cementing, mud putty and similar applications.

Cenospheres were earlier utilized in the United States as an extender for plastic compounds, as they are well matched with thermoplastics, Phenolic resins, Latex, Epoxies, Polyesters, and urethanes. The compatibility of Cenospheres with particular types of cements and adhesives coating and composites have been well identified.

PROVIDING THE ADVANTAGES OF

  • reducing weight,
  • less shrinkage and warping
  • Reduces water absorption.
  • increased filler loadings,
  • better flow characteristics,

PROJECT SPECIALTIES

Generally Cenosphere in India are being gathered from the ash ponds owing to its irrepressibility characteristics. These are skimmed out, washed, dried and sifted out as per customer’s specification for marketing. Due to immense requirement in international market for quality material, costs have gone up to a great extent whereas reach of collection from ash ponds still remains very limited without much reach for quality authority.

Well-nigh, all the ash ponds are now under control of local mafia who; for raw Cenosphere in India, charge high price without vouching any quality whatsoever. Besides quality discrepancies, collection from ash ponds remains stingy – leading to practice of mixing ash with Cenospheres without principle or scrupulous. WHEREAS in our developed process technology, one does not need to depend on collection from ash ponds at all and can extract Cenospheres right from the dry fly ash of thermal power plants. The process is a part of nanotechnology and a mergence of dry and wet process. By virtue of total control on the processes, one stands to extract reproducible quantity and quality of Cenospheres. The process generates zero outflowing and is therefore entirely non-polluting and ecofriendly.

We are a team of techno-research people having our roots in the India consecrated to the development of Cenospheres extraction and fly ash beneficiation.
