Synthesis and surface modification of rutile nanoparticles (NPs) are two distinct processes. Conventionally, they should be conducted separately. In this work, synthesis and surface modification of rutile NPs are consecutively performed in a designed microfluidic system, thereby avoiding the pilot processes, giving a high controllability and low-energy consumption of the process, and the preparation process of the coated TiO2 is simplified effectively. Samples synthesized using different strategies are compared, and the results demonstrate that the sample prepared using the microfluidic method shows a smaller particle size (60 nm) and a narrower particle size distribution range than those synthesized using the other two methods. Rutile NPs are most commonly used in terms of suspensions, the stability of the suspensions consisting of the naked and coated samples are assessed in terms of turbidity, agglomeration size, and settlement rate. Response surface methodology is employed to quantify the effects of the factors on the stability of suspensions.

The effect of alumina addition on the pore filling process, crystallization behavior and mechanical properties of silica‐based ceramic cores was investigated. The sintered samples at 1250 °C were treated at 1550 °C for 0.5 h in order to simulate a casting process condition. The microstructure analysis indicated that an appropriate alumina addition enhanced the pore filling process by supplying a substantial liquid viscous flow. With an increase in the liquid viscous flow, smaller pores were filled first, and larger pores were filled later. The results also indicated that the pore filling process could be enhanced by adding small powder additives to decrease the pore size between the particles in the ceramic material. However, an excessive alumina addition in the silica‐based ceramic cores had a negative effect on the flexural strength and leaching rate. As the alumina content increased from 8 to 12 wt%, the flexural strength of the ceramic core decreased from 16.37 to 4.60 MPa, respectively, and the leaching rate also decreased obviously. These results were explained by an acceleration in crystallization trend of the fused silica particle surface and the merging of connected pores in the sintered body.

Herein, we report on an efficient strategy to synthesize anatase nanoparticles in a spiral microreactor. The synthesized nanopowders were characterized by X-ray diffraction and high resolution transmission electron microscopy. L25(56) orthogonal experiments were performed in order to assess the effect of each factor on the particle size of anatase nanopowders. Finally, the residence time R value was 50.734, which was much larger than R values for other factors, highlighting residence time as the key factor determining anatase nanoparticle size.

The oxidation kinetics of low valence titanium and iron in Ti-bearing blast furnace slag were investigated, the activation energies were calculated, which are 461.1 and 437.3 kJ/mol, respectively. The results illustrate that the oxidation process of Ti3+ in the slag is controlled by chemical reactions. However, the chemical reaction between oxygen and iron, between slag and gas, is the determining step of the iron oxidation process. The effects of the isothermal oxidation on the content of Fe2O3, FeM, FeO, and FeT in the slag are discussed. The Fe2+ and Ti3+ in the molten slag were oxidized at high temperatures. Oxygen affinity of the slag can be described using oxygen capacity. The oxygen capacity of Ti-bearing blast furnace slag was investigated during the dynamic oxidation process, the results indicates that the oxygen capacity of the slag decreased with increasing oxidation time during the dynamic oxidation process.
