Abstract

"SìNTESE DO PIGMENTO DE óXIDO DE FERRO ENCAPSULADO EM MATRIZ DE SìLICA AMORFA". é processo de encapsulamento de óxido de ferro, obtido de um precursor deste, como a Goetita (FeOOH), possuindo um diâmetro de partícula médio variando de 1 a 3 <109>m, em uma matriz encapsuladora de Sílica Amorfa, com área superficial específica de 400 m^ 2^/g e um percentual desta na mistura de 10 a 90% em massa, calcinados a 1300<198>C, que pode ser utilizado na indústria cerâmica, em temperaturas na faixa de 1100<198>C, produzindo uma coloração rósea."SYNTHESIS OF IRON PIGMENT encapsulated in silica amorphous matrix". is an iron oxide encapsulation process obtained from an iron oxide precursor such as Goetite (FeOOH) having an average particle diameter ranging from 1 to 3 <109> m in an encapsulating matrix of Amorphous Silica with specific surface area 400 m ^ 2 ^ / g and a percentage thereof in the mixture of 10 to 90% by weight calcined at 1300 <198> C which may be used in the ceramic industry at temperatures in the range of 1100 <198> C to produce a pink coloration.
