Characterization of the Jordanian Feldspar Raw Materials for Application in the Ceramic and Glass Industries

摘要

In this study, Jordanian feldspar from Wadi Al-Jayshiah area was invested to evaluate its applicability as raw material for ceramic and industries. The chemical analysis indicated that the average Fe₂O₃ content is 2.33%, which is very high, compared to commercial ceramic and glass grades feldspar. The SiO₂ content in the Wadi Al-Jayshiah feldspar (67.96%) lies within the required amount in commercial ceramic grade feldspar (75%) and the in commercial ceramic glass feldspar (68.9 %). On the other hand it was found that the contents of K₂O and Na₂O are 4.13 and 4.12, respectively, which makes it suitable for the ceramic industry. However for glass in industry a beneficiation pre-treatment step is required to increase the amount of Na₂O.
