Show supersonic waves break solids by vibrations PORT HURON MICH ic waves sounds too shrill in pit pitch ch to 0 be heard b by y the human ear will soon be used to break up sol solid I 1 d particles into new degrees of fineness sounds new use has been developed from research of dr karl soellner of the department of agronomy at cornell university he found that high frequency sound waves not only make sediments gelband gels and precipitates disperse as previously had been known but also that certain solids having a laminated structure could be broken into fine bits by the intense vibrations created materials on which tie the supersonic waves work well include graphite mica and steatite As soon as production changes are completed colloidal co I 1 graphite will be made of much finer particle size and longer suspension than has heretofore been available to industry |
