Fig. 1 and Fig. 2 show the XRD pattern of both samples, showing the maximum peak of (111) matching with the reference card of CeO2 with number 00-043-1002.
And thus the more charges have accumulated around grain boundaries due to the occurrence of interfacial polarization at lower frequency.

Conversion Conditions of Grinding Mechanism for Difficult to Grinding Materials In Quick-point grinding process, both the grain depth of cut and the contact length is very little, and the process no longer generates debris at the brittle form completely for some brittle materials such as advanced ceramics because of impact and adiabatic shearing micro-damages, whereas the grinding mechanism is that the material is removed at ductility.

The storage of a large number of red mud both occupies land, waste resources and easily leads to environmental pollution.
Red mud with fine grain size, softness, strong plastic is similar to clay, which can be used to replace clay to produce brick [1].

The loosened grain material on the asphalt pavement shall impact the safety of driving during transit of automobile.
As the permanent airport, there are many methods for reporting bearing strength of pavement, e.g., the airplane total quality report, the allowable load of a main landing gear of airplane, the load class number method (LCN), the airplane classification method, the load classification grade (LCG) can all be used to report pavement strength[2], the commonly recognized method is ACN-PCN method proposed by International Civil Aviation Organization.

In addition to semi-coke the chemical products of pyrolysis (resin and gas) and sulfur compounds (pyrite crystals and pyrrhotite grains) with pronounced ferromagnetic properties and therefore easily extracted by magnetic separation are also obtained [6, 1].

Also, damping capacity of SMA depends directly on external variables such as heating rate, frequency and oscillation amplitude; and internal ones such as the type of material, grain size, martensite interface density, structural defects [4].
As this density increases, damping capacity gets higher until an optimum point, when the number of defects starts to prevent the movement of twin interfaces, responsible for damping behavior [3]. 20 40 60 80 100 120 140 0,000 0,005 0,010 0,015 0,020 0,025 0,030 0,035 Tan δ Temperature (°C) SMA NiTi Aluminum Stainless Steel Brass 300 320 340 360 380 400 Temperature (K) Figure 1.
