Cenospheres are microscopic hollow spheres that are formed in ash, especially when coal is burnt in power plants. They are characterized by their light, hollow structure, which gives them a low density. Cenospheres are used in various industries, including building materials, plastics and coatings, to make materials lighter and increase their strength. They are also an efficient filler material and can be used to improve insulation, damping and viscosity in various applications.
