What is the reason of keeping second step lower temperature in two step sintering of Titania?
Best insight from top research papers
In the two-step sintering process of Titania, the reason for keeping the second step at a lower temperature is to achieve enhanced densification without significant grain growth . This strategy exploits the difference in temperature sensitivity for densification and grain growth, allowing for improved densification while inhibiting excessive grain growth. By initially heating the specimen to a higher temperature and then cooling it for a longer duration at a lower temperature, full densification without notable grain growth can be achieved, resulting in nanostructured Titania ceramics with fine grain sizes and high relative density. This approach effectively suppresses accelerated grain growth during the final sintering stage, making it feasible to utilize Titania ceramics in structural and tissue engineering applications.

How does the sintering temperature of TiO2 affect the efficiency of DSSCs?5 answersThe sintering temperature of TiO2 significantly impacts the efficiency of dye-sensitized solar cells (DSSCs). Higher sintering temperatures, such as around 500°C, lead to improved efficiency in rigid DSSCs, with reported power conversion efficiencies (PCE) of 6.0-7.1%. However, in flexible DSSCs on polymer substrates, the substrate's temperature limit (~150°C) poses a challenge. Heat sink-assisted sintering allows for elevated sintering temperatures without compromising the polymer integrity, resulting in effectively sintered TiO2 films and enhanced photovoltaic performance, with increased PCE due to controlled temperature rise. Additionally, the size of TiO2 nanoparticles influences the sintering rate, with larger particles exhibiting higher lattice stability and reducing the overall sintering rate, impacting the efficiency of DSSCs.
What are the effects of pre-heat treatment on the performance of TiO2 DSSCs?5 answersPre-heat treatment of TiO2 films in dye-sensitized solar cells (DSSCs) has been found to have significant effects on their performance. Multiple sintering (MS) of the titania films during the heat treatment process has shown better performance in terms of higher efficiency for the corresponding DSSCs compared to single-step sintering (SS). Heat treatment of TiO2 coatings on touch surfaces has been shown to reduce pathogen viability, but the presence of co-deposited carbon in the coatings can interfere with the transport of radical oxygen species to the bacteria and reduce the active surface area. The annealing temperature during the heat treatment of TiO2 nanotubes (NTs) arrays has been found to improve the crystalline anatase quality, but also leads to the diffusion of Sn from the substrate to TiO2, which can play a role in increasing the photoperformance of TiO2 NTs/FTO based structures. Heat treatment assisted electrospinning of TiO2 compact layers has been shown to improve the power conversion efficiency (PCE) of DSSCs by reducing series resistance and improving charge collection efficiency. Heat treatment of TiO2-SiO2 composites has been found to have a minor effect on the photocatalytic activity, but is crucial for controlling the segregation of the two phases and promoting a synchronous effect between adsorption and photocatalysis.
Why does Underworld2 not consider temperature?5 answersUnderworld2 does not consider temperature because it is primarily focused on modelling long time-scale solid-Earth processes and capturing a system of large dynamic range. The software aims to resolve a large range of length scales and provide robust solution strategies for diverse rheological behaviors. While temperature may be an important factor in certain models and scenarios, it is not a primary focus of Underworld2, which prioritizes other aspects of solid-Earth processes.
How low temperature sintering of zirconia?5 answersLow temperature sintering of zirconia can be achieved through various methods. One approach is the introduction of additives such as sodium disilicate or sodium silicate, which promote liquid-phase sintering and decrease the sintering temperature of zirconia ceramics. Another method involves the use of amorphous hydrated zirconia combined with Spark Plasma Sintering at temperatures as low as 350 °C. Additionally, a method utilizing trace molten salt to form a liquid phase under low temperature has been proposed, inhibiting grain boundary migration and allowing for rapid sintering of fully stabilized zirconia powder. Two-step sintering has also been explored, where samples are sintered at a first step temperature followed by a decrease to a second step temperature, resulting in smaller grain sizes and narrower grain size distributions. These methods offer potential solutions for achieving low temperature sintering of zirconia ceramics.
Why is the band gap of TiO2 important?5 answersThe band gap of TiO2 is important because it determines the material's ability to absorb and emit light, which is crucial for various applications. Different factors can influence the band gap energy of TiO2, such as the crystalline phases, crystal size, and doping concentration. For example, the introduction of the Fe2O3 phase into TiO2 can decrease the band gap energy, allowing for better absorption of visible light. Similarly, H-substitution in graphdiyne (GDY) can increase the band gap energy, leading to improved charge separation and enhanced photocatalytic activity when GDY is hybridized with TiO2. Doping with Tb can also affect the band gap energy, with higher Tb concentrations resulting in lower band gap values. Understanding and controlling the band gap energy of TiO2 is essential for optimizing its performance in photocatalysis and other applications.
