Comments on the Quality of English Language

·       The phrase “TiO₂ content” is heavily overused, the abstract alone has it five times. I’d recommend varying the language a little to avoid overly repetitive wording

·       Introduction: The phrase “…demonstrated that the material loss process during the sintering treatment”, I think removal of the word “that” reads better in the context of the following sentences

Reviewer 2 Report

Comments and Suggestions for Authors

The manuscript titled "Effect of TiO2 on the Microstructure and Flexural Strength of Lunar Regolith Simulant" presents a comprehensive study on the impact of titanium dioxide (TiO2) concentrations on the properties of CUG-1A lunar regolith simulant. It effectively delineates the influence of TiO2 on phase transformations, microstructure, and macroscopic properties such as shrinkage rate, mechanical properties, and relative density. This research highlights the potential of TiO2 to enhance mechanical properties, specifically focusing on flexural strength and relative density, and offers insightful implications for in-situ resource utilization technology and lunar base construction.

For consideration in Ceramics, the manuscript would benefit from the following revisions:

1. Eliminate generic text in the methodology section for specificity and clarity.

2. Augment the discussion section with a more nuanced analysis of experimental results, including comparative studies for broader contextualization.

3. Address the long-term stability and durability of the modified regolith in lunar conditions.

4. Include an analysis of the impact of lunar environmental factors, like radiation and temperature fluctuations, on the modified regolith.

5. In Figure 1, introduce error bars for enhanced precision.

6. In Table 3, provide error margins for particle size measurements.

7. For Figure 3, specify the #PDF cards for all identified phases.

8. Clarify the temperatures marked in Figure 4, including their determination methods.

9. Improve the clarity of Figure 6 by cropping to focus on the main sample views, eliminating unnecessary blank spaces.

10. Add error bars to Figures 7 and 8 for improved data accuracy. 

These revisions would greatly enhance the manuscript's academic rigor and suitability for the targeted audience.
