It is all about cenosphere and its application
From a fly perspective, cenospheres containing alumina silicates are a particularly attractive ingredient. Although it is also obtained from lignite, it is an ash produced mainly by burning bituminous coal. Cenosphere is an attractive material for biomaterials due to its low bulk density, low density, high hardness, and complete chemical inertness. In particular, the topic of polycaprolactone and metal-ceramic composites has considerable potential applications. Based on the study of scientific data, it was found that the best seno spheres come mainly from Kazakhstan and India. Accurate determination of properties, their comparison, and their application are open issues worth investigating. This is due to the existence of suitable anthracite grades in these countries and the large reserves of different grades of cenosphere due to the energy supply system being predominantly coal-based. The fact that the use of such resources brings great ecological benefits, not just biomedical engine...
