Abstract
Si descrivono componenti ottici in ossido di silicio e/o altri ossidi metallici misti aventi precisione dimensionale che presenta tolleranze di rugosità superficiale e accuratezza profilometrica entro le specifiche descritte per gli intervalli di spettro visibile ed ultravioletto.I suddetti manufatti presentano dimensioni "finali" o "quasi - finali" essendo ottenuti per riduzione dimensionale isotropica (miniaturizzazione) di materiali monolitici amorfi, detti aerogeli, a loro volta preparati mediante tecniche di stampaggio a freddo basate su processi sol - gel.Si utilizzano tali oggetti particolarmente come accessori per trattamenti termici nell'industria elettronica o ceramica e/o come componenti e dispositivi ottici.
