“…This behavior may be due to the act of the higher heating temperature which induce weakening in grain boundaries between particles and causes numerous micro cracks and interstices throughout the structure which makes it easily grindable. This interpretation agrees with that suggested by Hariharan and Venkatachalam [14] and Pan et al [27]. Figure (2) illustrates also that increase of the percentage of -200 µm in the product of quartz is slightly higher than that of nepheline syenite from 500°c to 650°c.…”

“…Figure (2) illustrates also that increase of the percentage of -200 µm in the product of quartz is slightly higher than that of nepheline syenite from 500°c to 650°c. This behavior may be due to the phase transition of quartz from α to β as declared by Pan et al [27] and Martello et al [35].…”

“…For the ceramics industry it is finely ground typically >95% minus 43µm [25]. Silica sand and quartz are changeable in many different industries [26][27] as glass, ceramic, metallurgical and electronic, filler, foundry sand, abrasive, filtration media, engine sand, and electrical insulation. It is also used in ferrosilicon production.…”

In grinding practice, heterogeneous poli-mineral systems are more common than homogeneous mono-mineral system. The heterogeneity of raw materials in mineral beneficiation grinding circuit results by virtue of the varying properties of mineral constituents in an ore. In this investigation the effect of particle size and preheating conditions on the grindability of quartz as a mono-mineral ore, and nepheline syenite as a poli-mineral one was studied. 2n Factorial method was applied to arrange the studied parameters affecting the preheating of each of the two studied ores according to the importance of their relative effect on its grindability. The results revealed that incremented percentage of -200 µm in the preheated ground poli-mineral ore was less than that of monomineral one by about 32.9%. This behavior was interpreted by containing nepheline syenite on more than one mineral, consequently, phase change and anisotropic thermal expansion or contraction of the grain boundaries have a markedly effect on the grindability of preheated rocks, especially those contain more than one mineral.

“…Quartz has the characteristics of stable physical and chemical properties, wide distribution, and low cost, 1 and has been widely used in construction, 2 aerospace, 3 optical fiber communication, 4 military, and other fields 5 . However, quartz is transformed into cristobalite with a large coefficient of volume expansion at high temperatures, resulting in strong internal stress and cracks in the material, which greatly reduces the safe use performance of the material 6 …”

In order to inhibit the phase transition of quartz, the effects of BPO4 addition and sintering temperature on the structure and properties of quartz materials were studied. The results showed that the addition of 5 wt.% BPO4 successfully inhibited the formation of cristobalite. Samples with 5 wt.% BPO4 added exhibited the high cold modulus of rupture (15.59 MPa) and bulk density (1.92 g/cm3) sintered at 1200°C–1400°C. In addition, BPO4 formed a glass phase sintered at 1200°C–1400°C and distributed between SiO2 particles, filling pores and densifying the material. Therefore, the prepared quartz‐based ceramics with BPO4 have broad potential in the field of medium and high temperatures, and can be applied to aerospace and other fields.

As a consequence of rapid industrialization throughout the world, various environmental pollutants have begun to accumulate in water, air, and soil. This endangers the ecological environment of the earth, and environmental remediation has become an immediate priority. Among various environmental remediation techniques, piezocatalytic techniques, which uniquely take advantage of the piezoelectric effect, have attracted much attention. Piezoelectric effects allow pollutant degradation directly, while also enhancing photocatalysis by reducing the recombination of photogenerated carriers. In this Review, we provide a comprehensive summary of recent developments in piezocatalytic techniques for environmental remediation. The origin of the piezoelectric effect as well as classification of piezoelectric materials and their application in environmental remediation are systematically summarized. We also analyze the potential underlying mechanisms. Finally, urgent problems and the future development of piezocatalytic techniques are discussed.
