Abstract

Inventia se refera la un procedeu de obtinere a unui pigment de culoare verde smarald de tip uwarovit utilizat în industria ceramicei. Materia prima utilizata purtatoare de oxid de xalciu si oxid de siliciu este hidroxilicatul de calciu obtinut printr-o reactie de recipitare ce permite o reactivitate mare si oxid de crom sub forma de Cr sub 2 O sub 3, ce permit o ardere la o temperatura mai joasa de circa 1100 degree C.The invention relates to a process for obtaining a uwarovit green emerald pigment used in the ceramic industry. The raw material used X-oxide oxide and silicon oxide is calcium hydroxide obtained by a reaction reaction which allows a high reactivity and chromium oxide in the form of Cr below 2 O under 3, allowing a combustion at a higher temperature low at about 1100 degrees C.
