“…Delaying the initiation of the first‐stage thermal reaction to a higher temperature can be achieved by mixing the initial composition with α‐cordierite powders. Mixing will result in the addition of α‐cordierite particles that impede the migration of Al 2 O 3 or enstatite particles and prevent them from contacting and reacting with the corresponding particles 31,32 . The α‐cordierite particles mixed into the starting composition will share Al 2 O 3 particles with kaolinite and talc and remove certain amounts of Al 2 O 3 particles apart from the surface of the two particles, reducing the number of Al 2 O 3 particles attached to kaolinite and talc.…”

This study investigates a quasi‐synchronous solid‐state reaction for synthesizing cordierite powder using talc, kaolinite, and Al2O3 mineral powders as starting materials. The thermal reaction proceeded with 2 different stages according to the Al sources provided by: (1) Al2O3 powders: the 1st stage starting at temperatures which are considerably lower than 1150°C and (2) kaolinite (mullite): 2nd stage starting at temperatures which are higher than 1150°C. The goal is to shift the temperature of the first stage to coincide with that of the second stage by mixing α‐cordierite powder with the starting constituents. Exceeding the authentic reduction amounts of Al2O3 on talc particles leads to a rise in the temperature required to initiate the first stage reaction to 1200°C. However, this also eliminates the presence of β‐cordierite and spinel that occur in the first stage and allows for the early fulfillment of α‐cordierite formation in the second stage. The excess SiO2 released by the second stage compensates for the insufficient SiO2 required by the first stage, allowing for a smooth processing reaction. Also, the quasi‐synchronous solid‐state reaction for synthesizing cordierite occurs.This article is protected by copyright. All rights reserved

Surface modification by means of nanostructures is of interest to enhance boiling heat transfer in various applications including the organic Rankine cycle (ORC). With the goal of obtaining rough and dense aluminum oxide (Al 2 O 3 ) nanofilms, the optimal combination of process parameters for electrophoretic deposition (EPD) based on the uniform design (UD) method is explored in this paper. The detailed procedures for the EPD process and UD method are presented. Four main influencing conditions controlling the EPD process were identified as: nanofluid concentration, deposition time, applied voltage and suspension pH. A series of tests were carried out based on the UD experimental design. A regression model and statistical analysis were applied to the results. Sensitivity analyses of the effect of the four main parameters on the roughness and deposited mass of Al 2 O 3 films were also carried out.The results showed that Al 2 O 3 nanofilms were deposited compactly and uniformly on the substrate. Within the range of the experiments, the preferred combination of process -4 g/cm 2 , respectively. A verification experiment was carried out at these conditions and gave values of roughness and deposited mass within 8% error of the expected ones as determined from the UD approach. It is concluded that uniform design is useful for the optimization of electrophoretic deposition requiring only 7 tests compared to 49 using the orthogonal design method.
