Introduction Microstrip Ring Resonator (MRR) has been developed as a sensory device for the characterization of the dielectric properties of materials [1]-[4].
It is significant to accurately measure permittivity, including effective dielectric constant and loss factor of respective samples.
The measurement was affected by several factors such as mechanical and electrical imperfections of the ring [9].
The electric charge when placed in an electromagnetic field experiences force which pushes the respective property to the outer part of the ring from inner ring.

They possess superior mechanical properties and toughness but prone to wear and corrosion hence, they exhibited tribological properties make them susceptible to unexpected failure.
However, TiC is considered as the most due its high specific strength, chemical stability, high oxidation resistance and good mechanical bonding to the steel matrix [5].

It was determined that at the temperature of 1170 °C the expanded clay aggregate with high strength properties and a high coefficient of swelling is formed.
Industrial wastes actively affect not only the air but also the hydrosphere.
The authors noted that the viscosity of the mass is one of the main factors of the swelling process [15].
A number of scientific papers suggest that mullite gives the basic physical and mechanical properties to the ceramic materials [16 − 20].
Introduction of the electric steel melting slag in the composition of ceramic materials causes mullite formation, which increases physical and mechanical properties of expanded clay.

Kinetics; Activated carbon; Antimony; Adsorption Abstract: The affecting factors and kinetic characteristics of antimony (Sb) adsoption onto a type of the coconut shell activated carbon were investigated in this study.
Due to the stability of the physicochemical properties, resistance to acid and alkali, heatproof, and mechanical strength, activated carbon can be regenerated by a variety of methods to restore the adsorption capacity, which can greatly reduce the process cost of removal antimony from the polluted environment.

The results show that the charging voltage affects on the AlN content and the morphology of samples, significantly.
The mechanical strength of AlN is pretty high at room temperature and decreases slowly with the rise of temperature.
In addition, AlN is an important III–V nitride-based semiconductor with several excellent properties such as wide bandgap (6.2eV), high thermal conductivity (318-319 W/mK)[1] at low temperature, high volume resistivity, low dielectric constant, excellent thermal expansion coefficient and excellent chemical stability[2,3].
The quality of AlN powder is one key factor to prepare high-quality AlN ceramic.
