Study of the Addition Effect of Fe₂O₃ and Al₂O₃ Originated from Pectin Citrus in the Glassy Phase on the Microestructural Development and in the Mechanical Characteristics of the Triaxial Ceramics

Abstract:

Triaxial ceramics are multiphased materials produced from natural raw material. That a small modification as much concerning in the composition from raw material a ceramic mass, may change several properties from ceramics. Thus, was included into the ceramic mass Al₂O₃ and Fe₂O₃, however both originated from pectin citrus plus salt the intended respective metal source. These oxides have a particular physical characteristic as high softness and high porosity. In addition to the ceramic mass containing 10% of clay, 25% kaolin, 35% feldspar and 30% of alumina (Ind. Alcoa) was inserted 6% of Fe₂O₃ and the full replacement of commercial alumina by Al₂O_3(pec). The result from these oxides are satisfactory mainly. Influencing in thermal contraction, in the reduction of the residual porosity and changing the final color inthe product.
