Structural and Thermal Characterisation of Lithium Aluminium Titanium Tantalum Phosphate NASICON-type Solid Electrolyte

Abubakar Sadiq Sanda*, Mohammed Isah Kimpa, Ibrahim Sharifat Olalonpe, Isah Kasim Uthman

The material with NASICON-type structure lithium aluminium titanium phosphate with tantalum substituting titanium Li1.3Al0.3Ti1.66Ta0.04(PO4)3 (LATTaP) has been synthesised via the solid-state method at a sintering temperature of 900 ºC for 6 h. The thermal analysis indicated that the reaction of the chemical mixture becomes stable around 717 ºC, indicating an improvement in the material densifica...

Advances in Sol-Gel Synthesis of MgZr4(1-x)Hf4xP6O24 (x = 0, 1) Solid Electrolytes for Electrochemical Devices

Mohammed Alhaji Adamu*, Girish M Kale

The potential solid electrolytes, MgZr4P6O24 and MgHf4P6O24 were prepared using modified novel sol-gel method. Structural and electrical properties of the solid electrolytes were determined. TGA-DSC analyses indicated that the pure dried xerogel powders, when calcined at 900 oC converts to pure single phase MgZr4P6O24 and MgHf4P6O24 nanopowders with excellent crystallinity. Pellets of 13 mm diamet...

Development and Experimentation of Hybrid Composite Gasket Using Sawdust Ash, Waste Glass Powder, and Polyester Resin

Adekunle Nurudeen Olatunde*, Fasasi Rauf Olamide, Ismaila Salami Olasunkanmi, Daniel Samuel Damilare, Quadri Oluwaseun

The increasing environmental burden caused by industrial wastes has prompted the development of sustainable alternatives to conventional engineering materials. This study utilized sawdust ash, waste glass powder, and polyester resin to develop composite gasket materials, aligning with the principles of sustainability and circular economy. Five composite formulations were prepared with constant pol...
