Investigation of Structural, Morphological, Resistivity of Novel Electrical Insulator: Industrial Wastes

In the present study, the effect of china clays on the sintering, strength and dielectric behavior of electrical ceramic fly ash/china clay (FA/CC) composite insulator is investigated. The different composition of samples containing different china clay (CC) contents of 10, 20, 30, 40, and 50 % are prepared using the uniaxial pressure technique applying 10 MPa pressure. At 1200 °C, for the composition having 40 wt% china clays, the maximum resistivity is calculated and is 39.5 × 107 Ωm. The composite is highly competence with china clays-based insulators. Further, the prepared composite is also analysed using different characterization technique such as x-ray diffraction, field emission scanning electron microscopy with energy dispersive analysis, fourier transformation infra-red spectroscopy, dielctric, and thermo gravimetric analysis. Frequency dielectric value of the composite is estimated at room temperature in the frequency range of 1-500 kHz at room temperature. According to the resistivity and dielectric properties, the composite has enormous potential for the electrical insulator application.

Thar Desert and its Natural Resources: A Case Study of the District Tharparkar in Sindh Province of Pakistan

The research study aims to display natural resources of Thar Desert area ofdistrict Tharparkar in Sindh. It is being studied over the years that DistrictTharparkar is totaled as a richest district in natural resources, such as coal,granite, salt mines, china clay, livestock, range land forest and mushrooms.The topography of the District 99% area covered in the desert which is knownas the part of Thar Desert. The Thar Desert existed into two countriesPakistan and India. The discovery of Thar Coal Reserves is one of thesignificant developments in the history of Sindh province of Pakistan whichplaced country at 7th among world top 12 richest coal reserves countries dueto its economic worth. On the basis of the previous studies; it is expected thatThar coal reserves having the potential to solve the energy crisis of Pakistan.The availability of granite is 26.05 billion tons found into 8 to 10 differentcolors in the area of Nagarparkar. Moreover, China clay extracted at 12 to 14different locations and around 2000 people employed in the different fields.Thar Desert of Pakistan has around 120 salt lakes and around 400 laborerswere employed to harvest salt. The Rangeland forests in the desert area of thedistrict represents the main source of livelihood is livestock and the areas arehighlighted the most densely populated in livestock in Sindh province ofPakistan.

A Comparative Study on the Flocculation of Silica and China Clay with Chitosan and Synthetic Polyelectrolytes

Flocculation is still one of the most important and efficient processes for water treatment. However, most industrial processes, such as in water treatment plants, still use huge amounts of synthetic polyelectrolytes for the flocculation process. Here we compare the flocculation of two different suspended particles, i.e., silica particles and china clay, with the biopolymer chitosan and two common strong synthetic polyelectrolytes. As a flocculant, chitosan featured a minimum uptake rate of 0.05 mg/g for silica and 1.8 mg/g for china clay. Polydiallyldimethylammonium chloride (PDADMAC) for comparison possessed a minimum uptake rate of 0.05 mg/g for silica and 2.2 mg/g for china clay. Chitosan as an environmentally friendly biopolymer competes with the synthetic polyelectrolytes and thus represents a beneficial economic alternative to synthetic flocculants.
