Cenospheres also called microspheres, they are inert,hollow spheres and light weight fillers. And They have low density, nonpoisonous，corrosion-resisting, thermal stable, high partial strength, good insulating, sound isolating, low water absorption and low thermal conductivity. So they are used to reduce weight and increase the strength. Cenospheres are hollow ceramic microspheres found in fly ash, a natural byproduct of coal combustion during the generation of electric power. Small and hollow, microspheres are used as fillers or functional extenders in the manufacture of plastics, paints, resins; light weight aggregates for cement, ceramics and other construction products. Because Cenospheres often replace mined materials, they can significantly lower production costs. Simultaneously, cenosphere can benefit finished product properties by increasing durability and better sound proofing. Too, as material recycled from fly ash, cenosphere are environmentally friendly and help to preserve natural virgin fillers. As a portion of the fly ash generated in coal combustion, cenosphere are recycled from the waste stream. They are made up of inert silica, iron and alumina. Cenospheres have a size range from 1 to 300 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, micro balloons. The spherical shape of cenosphere improves flow ability in most applications and provides a more even distribution of the filler material. The natural properties of cenosphere make it possible to use them either in dry or wet slurry form. Cenospheres are easy to handle and provide a low surface area-to-volume ratio. Due to their inert properties, they are not affected by solvents, water, acids, or alkalis. Cenospheres are 75% lighter than other minerals currently used as a filler or extender.

Video: Cenospheres are lightweight, hollow, spherical particles that are derived from the ash produced during coal combustion in thermal power plants. In heat-resistant coatings, cenospheres serve several functions: Thermal Insulation: Cenospheres have low thermal conductivity, which means they are poor conductors of heat. When incorporated into heat-resistant coatings, they form a barrier that helps to reduce heat transfer. This insulation property helps to protect the underlying substrate from excessive heat and minimize thermal expansion. Lightweight Filler: Cenospheres have a low density, typically around 0.4-0.8 g/cm³, making them lightweight fillers. By adding cenospheres to coatings, their density can be reduced without sacrificing the coating's volume or thickness. This feature is particularly advantageous for reducing the overall weight of the coating, especially in applications where weight is a concern. Improved Thermal Shock Resistance: Cenospheres can enhance the thermal shock resistance of heat-resistant coatings. When exposed to sudden temperature changes, such as rapid heating or cooling, materials can experience thermal stress. The presence of cenospheres helps to distribute the stress more evenly, reducing the likelihood of cracking or delamination in the coating. Improved Mechanical Properties: Cenospheres can enhance the mechanical properties of heat-resistant coatings, such as hardness, tensile strength, and impact resistance. Their spherical shape and rigid structure contribute to reinforcing the coating matrix and improving its overall durability and toughness. Reduced Shrinkage and Warping: When heat-resistant coatings undergo thermal curing or drying processes, they may experience shrinkage and warping. By incorporating cenospheres into the coating formulation, these issues can be mitigated. Cenospheres act as internal voids, compensating for the shrinkage and reducing the likelihood of cracking or distortion. Overall, cenospheres play a significant role in heat-resistant coatings by providing thermal insulation, reducing density, enhancing thermal shock resistance, improving mechanical properties, and minimizing shrinkage and warping.
