4. Conclusion
In this study, zircon was decomposed with NaOH at different
temperatures and decomposed product (Na2ZrSiO5 and
Na2ZrO3 phases) was used as raw materials in order to produce
zircon pigments. Temperature was found to be a very important
factor in the decomposition of zircon with NaOH. Zircon
phases were completely disappeared at 850 ◦C, but reformed at
