Pierre indienne (granit noir indien pour outils de mesure de pr\u00e9cision \/ gabbro import\u00e9) Composition principale
La \u00ab pierre indienne \u00bb, utilis\u00e9e dans l'industrie pour la fabrication de plates-formes d'inspection du marbre et du granit ainsi que de socles de machines \u00e0 mesurer tridimensionnelles (MMT), est essentiellement un gabbro \u00e0 diorite \u00e0 grain fin, souvent class\u00e9 parmi les roches intrusives basiques de couleur fonc\u00e9e.<\/p>\n\n\n\n

I. Composition min\u00e9rale principale (en pourcentage)
Plagioclase : 55%\u201365% (primaire)
Plagioclase de calcium et de sodium, cristaux tabulaires, qui conf\u00e8rent \u00e0 la pierre sa structure dense, sa grande duret\u00e9 et sa faible d\u00e9formation.
Pyrox\u00e8ne (pyrox\u00e8ne commun) : 25%\u201335%
Min\u00e9ral fonc\u00e9, qui constitue la couleur noire de base et renforce la densit\u00e9 et la rigidit\u00e9.
Biotite : 3%\u20138%
Min\u00e9ral fonc\u00e9 en paillettes, pr\u00e9sent en petites quantit\u00e9s, qui alt\u00e8re le polissage et la couleur.
Olivine, magn\u00e9tite, ilm\u00e9nite : en quantit\u00e9s infimes
Une densit\u00e9 et une absorption de la lumi\u00e8re accrues, qui conf\u00e8rent \u00e0 l'Indian Stone sa couleur noire pure, parsem\u00e9e de quelques taches blanches.<\/p>\n\n\n\n

II. Composition chimique (principales gammes d'oxydes)
SiO\u2082 (silice) : 48%\u201352% (roche basique, teneur en silicium relativement faible)
Al\u2082O\u2083 Oxyde d'aluminium : 15%\u201318%
CaO (oxyde de calcium) : 8%\u201311%
MgO (oxyde de magn\u00e9sium) : 6%\u20139%
FeO Fe\u2082O\u2083 Fer total : 8%\u201312%
Na\u2082O, K\u2082O : 2%\u20134% Oligo-\u00e9l\u00e9ments alcalins<\/p>\n\n\n\n

III. Corr\u00e9lation des propri\u00e9t\u00e9s fondamentales (Pourquoi cette approche convient-elle aux plateformes de pr\u00e9cision ?)
Particules min\u00e9rales \u00e0 grain fin, uniformes et \u00e0 cristallisation dense
Structure exempte de porosit\u00e9 et de fissures, pr\u00e9sentant de faibles contraintes internes
Faible coefficient de dilatation thermique, absorption d'eau extr\u00eamement faible et r\u00e9sistance \u00e0 la d\u00e9formation
Excellente finition miroir apr\u00e8s polissage, couleur de fond noir pur avec tr\u00e8s peu d'impuret\u00e9s blanches, plus homog\u00e8ne que la pierre de Zhangqiu et les mat\u00e9riaux du Nord-Est<\/p>\n\n\n\n

IV. Distinction simple de composition par rapport au \u00ab Jinan Black \u00bb
Jinan Black : il s'agit \u00e9galement d'un gabbro, compos\u00e9 principalement de plagioclase et de pyrox\u00e8ne, pr\u00e9sentant une densit\u00e9 plus \u00e9lev\u00e9e, des cristaux plus fins et une plus grande stabilit\u00e9 ;
Pierre indienne : composition similaire avec des proportions min\u00e9rales l\u00e9g\u00e8rement diff\u00e9rentes ; performances globales proches de celles du \u00ab Jinan Black \u00bb, avec un meilleur rapport qualit\u00e9-prix.<\/p>\n\n\n\n
