S\u0131cak presleme sinterleme silisyum karb\u00fcr seramik, y\u00fcksek yo\u011funluklu silisyum karb\u00fcr seramik haz\u0131rlaman\u0131n en etkili yollar\u0131ndan biridir. S\u0131cak preslenmi\u015f silisyum karb\u00fcr\u00fcn \u00f6zellikleri genellikle reaksiyon sinterlenmi\u015f ve bas\u0131n\u00e7s\u0131z sinterlenmi\u015f silisyum karb\u00fcr\u00fcn \u00f6zelliklerinden daha y\u00fcksektir, \u00f6zellikle ince taneleri, y\u00fcksek kompaktl\u0131\u011f\u0131 ve \u00fcr\u00fcnlerin y\u00fcksek mukavemeti ve sertli\u011fi.<\/p>\n
