Changes in Morphology Caused by Mass Transfer Phenomenon

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

In this work, diverse changes in morphology caused by mass transfer phenomenon were investigated. I recommend the publication of this manuscript after minor revision.

 

The followings are the comments in detail:

1) It’s better to use the third person.

2) Line 26 Si-based ceramics?

3) In introduction, the motivation and important (difference) of this work should be further presented.

4) How to get the element composition in Table 1? The sum of all elements is not one hundred.

5) Line 113 Chemical equations should be numbered.

6) Section 4 can be moved into section 1.

7) There is a lack of conclusion section.

For reviewer 1

Thanks for your kind comments. According to your comments, I revised my manuscript as follows.

1. It’s better to use the third person. (Answer) I removed “We” from the sentence.
2. Si ceramics? (Answer) This word was changed to “Si contained”.
3. In introduction ------ (Answer) I changed the Introduction.
4. How to get the element composition ----- (Answer) Table 1 was deleted. As oxygen content was measured using LECO apparatus. So, in Experiment section, the content was added.
5. Chemical equations should be numbered (Answer) I revised them.
6. Section 4 can be moved into section 1 (Answer) I added “Conclusion section”. And the content of Section 4 was inserted in the conclusion section.
7. There is a lack of conclusion section. (Answer) I added the conclusion section.

 

Reviewer 2 Report

Comments and Suggestions for Authors

This research deals with the morphology changes caused by the mass transfer phenomenon.

Some recommendations and changes are listed to improve the quality of the paper.

In the title, the term “diverse” is very general and gives us little information about the involved processes. I recommend eliminating it from the title.

In the abstract, please clearly describe the problem to be solved, how this work can fulfill it, the novelty of your work, and the most important findings in a quantitative way.

“causes a lot of morphological changes” is a very vague idea. Please check.

“can be classified in this category”, which category?

In the introduction:

Figure 1 is difficult to read and follow in its current state. Please improve it. The footnote is the same as the figure title.

Use the same format for temperature (°) in the text. Separate thousands with commas (2000°C to 2,000°C)

“such as ceramic matrix composites (CMCs) using silicon carbide (SiC) fibers”. Define the acronym the first time that was used and only one time.

Change wt% to wt.% or Wt.%. The same with at% (at.% or At.%).

To improve understanding of the material synthesis process, the most important conditions can be described in the form of a comparative illustration (Fig. x). It is difficult to follow the preparation route in text form.               

“The fine structure". What do you mean by fine?

“was observed using field emission scanning electron microscopy (FE-SEM), model JSM-700F (JEOL, Ltd.), and transmission electron microscopy (TEM) in conjunction with energy-dispersive spectroscopy (EDS), model JEM-2100F (JEOL, Ltd.). Please remember that microscopy is the technique, and the microscope is the device. Please change microscopy by microscope.

NEWTONIAN Pascal-40. Please describe the used device.

In results:

“Each of these grain boundary structures was unique.", text without useful information, please rewrite the idea or remove the phrase.

Images in Fig. 2B are overlapped. Please check.

How the composition of Table 1 was obtained? Please add the corresponding deviation for comparison purposes.

In Fig. 4, change "=" to → in the chemical equations.

In Fig. 5, the result is not shown; only the spectrum.

Some footnotes do not finish with a dot. Please check.

Please separate magnitude from scale (6GPa to 6 GPa. 50nm to 50 nm, etc.).

There is no conclusion part with a summary related to the solved problem and the most important findings in a quantitative form.
