“…4. According to the Hund's rules, when the electronic structure is in the condition of entire empty, half or full filling, the ion has a steady state [12]. The Ce atom with 4f 1 5s 2 5p 6 5d 1 6s 2 electronic configuration is inclined to lose the electron of 4f electronic orbit to form stable Ce 4+ and occupies the A-site.…”

“…The two raw materials (MnO2 and CeO2) are the oxides, which have good chemical stability and durability, excellent abrasion, corrosion resistance, as well as high melting-point. Moreover, the potential advantages of the dual-doping of Ce/Mn reside in: (1) the Ce 4+ ions may enter into lattice position and alter the cationic distribution in the LaAlO3 structure [12]. (2) The doped Mn 4+ can be induced into lower valence in the presence of Ce.…”

“…On the other hand, "glass-ceramic" has a high potential for application, with excellent thermal, mechanical, chemical, biological and dielectric properties, becoming a target of great technological interest [7][8]. The process of glass powder recycling is based on the theory of glass-ceramic transformation by the nucleation and growth of crystals in its glass matrix [9].…”

The objective of this work is the production and characterization of glass-ceramic with recycled glass powder and 4% (w/w) of cerium dioxide. Eleven groups were defined with conformation pressure of 11.6 and 25.8 MPa, and cerium dioxide addition. The sintering temperatures of 650, 675, 700 and 750 °C were used. The raw material was formed into a mold with a uniaxial pressure. The density was measured by the Archimedes principle. The water absorption of the groups was also determined, as linear contraction percentage and the crystalline structure. The flexural strength was obtained by the three-point bending test and the results analyzed by the Weibull analysis. The specimens presented density ranging from 1.99 to 2.38 g/cm3. Increasing the temperature provided an increase in the density of the specimens and the flexural strength. At higher sintering temperature, this behavior was not observed. The highest flexural strength was 63.55 MPa, obtained at the sintering temperature of 700 ºC, conformed with 25.8 MPa, only glass powder. The increase in the forming pressure favored crystallization. The addition of cerium dioxide favored for the increase density and the Weibull modulus, but decrease of the flexural strength.

“…Tourmaline, with the chemical formula of NaR 3 Al 6 (-Si 6 O 18 )(BO 3 ) 3 (OH,F) 4 (R is Mg, Fe, Li, or Mn) [3][4][5], is a natural cyclosilicate mineral. Because of its special chemical structure, it possesses many unique physical and chemical properties [6], such as far-infrared radiation [7,8] and negative ion release [9,10]. As such, a variety of applications of tourmaline have been developed [11][12][13][14][15][16].…”

Tourmaline was modified with vinyl triethoxysilane containing double bond to prepare the polymerizable organic vinylsiliconoxyl tourmaline (VST) and then copolymerized with methyl methacrylate (MMA) and butyl acrylate (BA) to produce the tourmaline-containing functional copolymer p (VST/MMA/BA). The structures and morphologies of VST and p (VST/MMA/BA) copolymer were characterized by IR, SEM, and EDX. The experimental results indicated that tourmaline was introduced into the copolymer via surface modification and the tourmaline-containing functional copolymer was obtained by a copolymerization process with MMA and BA. The prepared p (VST/MMA/BA) copolymer displayed excellent storage stabilities, high far-infrared radiation and negative ion releasing performances, and good mechanical properties.
