Fe-Cr Siyah Seramik Pigment Üretiminde Ferrokrom Kullanımı

Bu çalışmada, saf oksitlere göre daha ucuz hammaddeler kullanarak porselen karo bünyeleri için siyah Fe-Cr hematit pigmentlerin üretimi ve karakterizasyonu amaçlanmıştır. Hematit ve ferrokrom ile üretilen pigmentlerin L*a*b* renk değerlerine; başlangıç hammaddelerinin tane boyutu, mineralleştirici ilavesi ve kademeli kalsinasyonun etkisi incelenmiştir. Üretilen pigmentlerin renkleri spektrofotometre ile ölçülerek L*a*b* olarak ifade edilmiştir. İnce tane boyutuna sahip başlangıç hammaddeleri ve mineralleştirici ilavesi ile kademeli olarak kalsine edilerek üretilen pigmentlerin renk parametrelerinin, ticari olarak kullanılan siyah pigmentlerle oldukça benzer olduğu tespit edilmiştir.

Use Of Ferrochrome In Fe-Cr Black Ceramic Pigment Production

In this study, production and charecrarization of Fe-Cr hematite black pigments for porcelain tile bodies were attempted by using cheaper raw materials as compared to pure oxides. Effect of raw material particle size, mineralizers and stepwise calcination on pigments L*a*b* values that produced with hematite and ferrochrome were investigated. The obtained colour values were reported as L*a*b values, measured by a spectrophotometer. When fine particle size raw materials with mineralizers were used and calcined in a stepwise manner, black ceramic pigment with very similar colour parameters to commercial black pigments was produced.
