Recycling of waste titanium slag to functional glass ceramics; the effect of Bi2O3 on physical, structural, optical and radiation shielding properties
The design and development of functional materials from industrial waste materials for environmental sustainability has received critical attention in recent decades. This study successfully developed environmentally clean glass ceramics using titanium slag through the conventional melt quenching technique. The influence of the incorporation of Bi2O3 at 10, 20 and 30 % on density, open porosity, water absorption, phase composition, structure, microstructure, optical properties and radiation shielding properties of the glass ceramic were investigated. The results showed that all sintered glass ceramics contained crystalline phases such as diopside, clinopyroxene or titanian aluminian and rankinite. Incorporating Bi2O3 resulted in the crystallization of calcium bismuth titanate (CBT) which increased the density of the glass ceramics and improved the microstructure leading to reduced open porosity and water absorption. The T6S1B3 sample exhibited 18.13 % lower band gap, 9.80 % higher refractive index and 20.59 % higher dielectric constant. At 0.1 MeV, T6S1B3 recorded a mass attenuation coefficient of 1.6798 cm2g-1 which is 733.5 % higher than T9S1. Similarly, higher HVL and MFP values both at 30.7 % was obtained at 1MeV. Therefore, this presents a pathway to utilize waste titanium slag to develop glass ceramics with characteristics that are effective in remediating hazardous concerns with ionizing radiations and possess good non-linear optical properties.
期刊介绍:
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
