In this study, transparent Nd: YAG ceramic was fabricated by gel casting of iso bam system using a dispersant composed of tetramethylammonium hydroxide (TMAH) to modify the rheological properties of slurry. The effects of dispersant content on the dispersibility and viscosity of slurry were studied, as well as the microstructure and light transmittance of the obtained transparent ceramics were also analyzed through the introduction of 0 − 1.5 wt.% TMAH. The results showed that the dispersion mechanism of TMAH is mainly to control the electrostatic property and the alkaline Zeta potential value of the slurry. The electrostatic repulsion of ceramic particles in the slurry could be effectively increased through the dispersing action of the additive, thereby reducing the viscosity of the slurry and improving the fluidity of the slurries. Under the TMAH content of 1 wt.%, a high-fluidity and good dispersion of Nd: YAG slurry with a solid load of 78.8 wt.% was obtained. A low viscosity of 72.89 mPa·s was achieved under shearing of 100 s-1, and a dense uniform body was obtained by self-gelling reaction. Highly transparent Nd: YAG ceramics were obtained after vacuum reaction sintering at 1780°C for 10 h, with a transmittance of 75.12% at 1064 nm. In all, the TMAH dispersant could effectively improve the molding properties of PIBM single system gel injection molding transparent ceramics. © 2022 SPIE.

The self-curing mechanism of water-base self-curing sand-casting coating is described. The relationship between the moisture content and the self-curing time of the coating is analyzed on the basis of the principle of non-isometric ball stacking and verified experimentally. The influence law and cause of the size-distribution and morphology of refractory-aggregate particle on self-curing time of coating is studied based on experiments. The results show that: the moisture content of the coating has an approximate linear relationship with the self-curing time of the coating, the particle-size distribution of refractory-aggregate has a significant effect on the self-curing time, while the particle size has little effect. The particle size of refractory aggregate should be normally distributed with an average particle size of 200 mesh to 325 mesh. The particle morphology of the refractory aggregate also significantly affects self-curing time of the coating, the coating prepared by the powder quartz whose grain shape is similar to the spherical shape has a low moisture content and the coating can cure quickly. The coating with a thickness of 0.5mm can achieve self-curing within 100 minutes under an environmental condition of a relative humidity of 80%±2%, which is expected to meet the production requirements of resin sand casting under high humidity climate conditions in South China. © 2023 SPIE.

Conductive hydrogels based on biopolymers have potential applications in the field of wearable devices,implantable devices, and human-machine interfaces due to their biocompatibility as well as ***, hydrogels are prone to water loss under dry atmospheres. In this paper, a biopolymer-based pressure sensor with water retention was designed. Xanthan gum(XG) and pullulan(P) were cross-linked with sodium trimetaphosphate(STMP) to prepare XG5-P-STMP, and polyethylene glycol with a molecular weight of 200(PEG200) was added into hydrogels to improve moisture retention. The mechanical properties of the hydrogels were investigated by rheologic measurements such as time sweep, frequency sweep, and strain sweep. The results showed that the addition of PEG200 enhanced strength and moisture retention of the hydrogels, and high PEG200 content hindered the recovery property of the hydrogels. Furthermore, the XG5-P-PEG-STMP hydrogel with ionic conductivity and recoverability was explored as a pressure sensor, and the resistance change ratio exhibited repeatable profile. This work provides some valuable information for further applications of natural polysaccharides as intelligent flexible elections.
