“…The intensities of these peaks were enhanced with increasing the calcinations temperature. In fact, the most stable cobalt oxide at room temperature is the mixed-valence of Co 3 Figure 2B showed the Raman spectra of the TiO 2 @-CoAl 2 O 4 complex pigments calcined at 800 and 1100°C, respectively. As seen from the curve a, the peaks at 241, 449, and 612 cm À1 were attributed to two-phonon scattering, E g and A 1g modes of rutile TiO 2 , respectively.…”

“…Nowadays, inorganic pigments are widely applied in manufacturing porcelain, ceramic tiles, enamels, paints, plastic, interior, and exterior coating, due to its high durability and color stability under extreme conditions such as UV radiation, temperature, or chemical attack . Among inorganic pigments, the cobalt blue is an important family of pigments with an intense blue color, and mainly consists of cobalt aluminates (CoAl 2 O 4 ) with a spinel structure, which is commonly known as Thenard's blue.…”

“…Cobalt aluminate (cobalt blue, CoAl 2 O 4 ) is a spinel type structure blue eco-friendly pigments with excellent thermal and chemical stability, and it has been widely used in the fields of ceramics, plastics, paint, rubber and glass (Jafari and Hassanzadeh-Tabriz, 2014; Álvarez-Docio et al, 2017; He et al, 2017; Yoneda et al, 2018). Therefore, cobalt blue may be expected to develop the high-performance anticorrosion coating, especially for acetic acid-salt fog corrosion.…”
