Abstract

L'INVENTION SE RAPPORTE AU DOMAINE DE LA CROISSANCE ET DU TRAITEMENT DE MONOCRISTAUX. LE CARBURE DE SILICIUM OBTENU PAR CE PROCÉDÉ PEUT ÊTRE UTILISÉ NON SEULEMENT DANS L'INDUSTRIE ÉLECTRONIQUE OU EN JOAILLERIE, MAIS AUSSI EN QUALITÉ DE VERRE OU POUR DES BOÎTIERS DE MONTRES. CE PROCÉDÉ CONSISTE À FAIRE CROÎTRE SIMULTANÉMENT PLUSIEURS ÉBAUCHES DE CRISTAUX DE MOISSANITE DE FORME CELLULAIRE DE GRAPHITE DE FORMATION, PUIS À LES SÉPARER EN CRISTAUX DISTINCTS, À LES TAILLER, À LES FAÇONNER ET À LES POLIR. AVANT LA TAILLE, LE FAÇONNAGE ET LE POLISSAGE, ON PROCÈDE À UNE OPÉRATION D'ÉTIQUETAGE DES ÉBAUCHES SUR UN SUPPORT, PUIS DE RÉ-ÉTIQUETAGE DES ÉBAUCHES SUR LEUR CÔTÉ OPPOSÉ. LE POLISSAGE SE FAIT EN POLISSANT LA MOISSANITE SUR UNE MEULE CÉRAMIQUE TOURNANT À UNE VITESSE DE 200 À 300 TOURS/MINUTE, EN UTILISANT DE LA POUDRE DE DIAMANT (PULVÉRISATION) DONT LA TAILLE DES GRAINS VARIE DE 0,125 À 0,45 MICROMÈTRES, ET EN S'ASSURANT QUE LA PROFONDEUR DES CAPILLAIRES SOIT INFÉRIEURE À LA LONGUEUR DE L'ONDE LUMINEUSE DE LA PARTIE VISIBLE DU SPECTRE. LES ARÊTES COUPÉES ET ÉBRÉCHÉES AINSI QUE LES ÉBAUCHES PRÉSENTANT DES DÉFAUTS ET NON APTES À LA TAILLE SONT BROYÉES ET RENVOYÉES À L'ÉTAPE DE CROISSANCE.
