Carburo di silicio nero per abrasivi
Il carburo di silicio nero è un materiale altamente resistente e tagliente, noto per la sua estrema durezza e conduttività termica. Viene comunemente utilizzato in applicazioni che richiedono un taglio, una rettifica o una finitura superficiale efficaci, soprattutto su materiali duri come ceramica, metalli e vetro. La sua elevata resistenza all'usura e al calore lo rende prezioso anche nell'industria degli abrasivi e dei refrattari.
