How many times does the grain of alumina increase after traditional sintering from the powder?5 answersThe grain size of alumina increases significantly after traditional sintering from the powder. Research indicates that the grain growth behavior in alumina compacts during sintering falls into two distinct regions. In the region where the porosity remains interconnected, grain growth is negligible; however, when the continuous pore network collapses into isolated pores, grains grow rapidly. This transition in grain growth behavior is observed at around 90% of theoretical density. Additionally, the final grain sizes of alumina can increase after post-HIP treatment, depending on the HIPing temperature or presintering temperature, with maximal strength reaching about 650 MPa when the grain size is around 1 μm.
How can one sinter SiO2 or CaCO3 powders at low temperatures in a muffle furnace?5 answersTo sinter SiO2 or CaCO3 powders at low temperatures in a muffle furnace, various methods can be employed. For SiO2, a low-temperature sintering process can be achieved by utilizing a sintering aid prepared from zinc powder, zinc fluorosilicate, and strontium aluminoborate, followed by sintering at 460 to 470°C for 2 to 3 hours. On the other hand, for CaCO3, the formation of CaO·SiO2 during high-temperature sintering can be controlled by adjusting the molar ratio of CaCO3 to SiO2, with CaO·SiO2 forming at lower temperatures through phase transition reactions. Additionally, the use of sintering additives like YbF3 and CaF2 can facilitate low-temperature sintering of ceramics like Si3N4 at 1550°C, enhancing phase transition rates and improving material properties.

What are the fact about sintering phenomenon ?5 answersSintering is a phenomenon that involves the heating and consolidation of materials. It is influenced by various factors such as the presence of heat evolution, driving forces, and the role of dislocations, grain boundaries, and pores. Deformation and diffusion processes during sintering have been extensively studied, particularly in relation to the shrinkage of silver, copper, and nickel powders. In chemically heterogeneous systems, inter-diffusion between particles during sintering can lead to the formation of transient nonequilibrium phases, which can significantly affect microstructure and volume changes. The sintering phenomenon has also been observed in portland cement pastes, where it contributes to contractive deformation and changes in strength, volume, and specific surface area. Overall, sintering is a complex process that involves the consolidation and transformation of materials, and its understanding is crucial for various applications in materials science and engineering.

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.
