Abstract
SE PRODUCEN GRANDES CRISTALES DE DIAMANTES EN UN RECIPIENTE DE REACCION QUE CONTIENE UN MATERIAL SEMILLA (30) NO DIAMAMNTE CRISTALINO ENLAZADO TETRAEDRICAMENTE, SEPARADO DE UNA FUENTE (26) DE CARBON PRACTICAMENTE PURO POR UNA MASA (24) DE DISOLVENTE/CATALIZADOR METALICO PARA SINTESIS DE DIAMANTES. LA DISPOSICION ES TAL QUE SE CREA UN GRADIENTE DE TEMPERATURAS ENTRE EL MATERIAL SEMILLA (30) Y LA FUENTE DE CARBON (26) BAJO LAS CONDICIONES DE TEMPERATURA Y PRESION APLICADAS, TAL QUE EL MATERIAL SEMILLA SE LOCALIZA EN UN PUNTO PROXIMO AL VALOR MINIMO DE TEMPERATURA PARA EL GRADIENTE, Y LA FUENTE DE CARBON SE LOCALIZA EN UN PUNTO PROXIMO AL VALOR MAXIMO DE TEMPERATURA PARA EL GRADIENTE DE TEMPERATURAS. EJEMPLOS DE MATERIAL SEMILLA NO DIAMANTE ADECUADOS SON NITRURO DE BORO Y CARBURO DE SILICIO-(ALFA) CUBICOS.
