Abstract

Un compacto sinterizado tiene un primer material, un segundo material, y un tercer material. El primer material es nitruro de boro cúbico. El segundo material es un compuesto que incluye circonio. El tercer material es un óxido de aluminio y el óxido de aluminio incluye un óxido de aluminio de partícula fina. El compacto sinterizado tiene una primera región en donde no menos de 5% en volumen y no más de 50% en volumen del óxido de aluminio de partícula fina se dispersa en el segundo material. Sobre líneas rectas arbitrarias en la primera región, un valor promedio de distancias continuas ocupadas por el óxido de aluminio de partícula fina es no más de 0.08 µm y una desviación estándar de las distancias continuas ocupadas por el óxido de aluminio de partícula fina es no más de 0.1 µm.
