Piedra india (granito negro indio para instrumentos de medici\u00f3n de precisi\u00f3n \/ gabro importado). Composici\u00f3n principal
La \u00abpiedra india\u00bb, utilizada en la industria para plataformas de inspecci\u00f3n de m\u00e1rmol y granito y bases de m\u00e1quinas de medici\u00f3n por coordenadas (CMM), es esencialmente un gabro o diorita de grano fino, que a menudo se clasifica como una roca intrusiva b\u00e1sica de color oscuro.<\/p>\n\n\n\n

I. Composici\u00f3n mineral principal (porcentaje)
Plagioclasa: 55%\u201365% (primaria)
Plagioclasa de calcio y sodio, con cristales tabulares que determinan la estructura densa de la piedra, su elevada dureza y su m\u00ednima deformaci\u00f3n.
Piroxeno (piroxeno com\u00fan): 25%\u201335%
Mineral oscuro que constituye el color negro de base y que potencia la densidad y la rigidez.
Biotita: 3%\u20138%
Mineral oscuro en forma de escamas, presente en peque\u00f1as cantidades, que afecta al pulido y al color.
Olivina, magnetita, ilmenita: cantidades traza
El aumento de la densidad y la absorci\u00f3n de la luz dan como resultado el color negro puro de la piedra india, con pocas manchas blancas.<\/p>\n\n\n\n

II. Composici\u00f3n qu\u00edmica (intervalos principales de \u00f3xidos)
SiO\u2082 (s\u00edlice): 48%\u201352% (roca b\u00e1sica, con un contenido de silicio relativamente bajo)
Al\u2082O\u2083 \u00d3xido de aluminio: 15%\u201318%
CaO \u00d3xido de calcio: 8%\u201311%
\u00d3xido de magnesio (MgO): 6%\u20139%
FeO Fe\u2082O\u2083 Hierro total: 8%\u201312%
Na\u2082O, K\u2082O: 2%\u20134% Oligoelementos alcalinos<\/p>\n\n\n\n

III. Correlaci\u00f3n de propiedades fundamentales (por qu\u00e9 es adecuada para plataformas de precisi\u00f3n)
Part\u00edculas minerales de grano fino, uniformes y densamente cristalizadas
Estructura sin porosidad ni grietas, con baja tensi\u00f3n interna
Bajo coeficiente de dilataci\u00f3n t\u00e9rmica, absorci\u00f3n de agua extremadamente baja y resistencia a la deformaci\u00f3n
Excelente acabado especular tras el pulido; color de fondo negro puro con muy pocas impurezas blancas; m\u00e1s uniforme que la piedra de Zhangqiu y los materiales del noreste.<\/p>\n\n\n\n

IV. Distinci\u00f3n en cuanto a la composici\u00f3n simple respecto al \u00abJinan Black\u00bb
Jinan Black: tambi\u00e9n es un gabro, compuesto principalmente por piroxeno plagioclasa, con mayor densidad, cristales m\u00e1s finos y mayor estabilidad;
Piedra india: Composici\u00f3n similar con proporciones minerales ligeramente diferentes; rendimiento general similar al del \u00abJinan Black\u00bb, con una mejor relaci\u00f3n calidad-precio.<\/p>\n\n\n\n
