Round 1

Reviewer 1 Report

Paper needs to be improved in following manners, this is a nice study however, following

questions are necessary to be answered before further processing

a. This would be beneficial if authors could provide more details at the end of introduction

specifically stating the objective of the paper, although this is explained but needs a little more

clarity.

b. Authors need to update the survey of literature for more recent papers specifically published in

the recent years 2022 etc.

The authors should elaborate on their new findings that are worthy of consideration for publication in a journal.

c. Language of the paper needs professional touch ups as there are typos and errors in some parts

of paper and they need to be reduced.

d. In the conclusion section, authors need to focus on the outcomes of their study with salient

findings only, keep them brief, as more explanation is already added in the results and

discussion section.

e. Results and discussion section is well explained, please try to look at figures in this section they might need more explanation if needed.

 

f. Altogether after these improvements are properly made, paper would be in a decent shape and

can be considered for publication if revised well.

 

g. Please give a bird eye view picture of your finding in abstract.

Reviewer 2 Report

This manuscript studies the effect of oxygen dissolution on thermal- and electrical-conductivity of AlN by Al solid-state NMR analysis. The thermal dissipation and resistance characteristics of AlN ceramics were explained from the perspective of the microscopic local structure of defects. Some interesting results were found. This manuscript could be accepted for publication after a mandatory revision. The comments are as following:

1.  The authors explained the thermal dissipation and resistance properties of AlN ceramics from the perspective of the microscopic local structure of defects, and suggest that the concentration of dissolved oxygen affects the thermal conductivity and insulation properties of AlN ceramics. Please explain in detail how the change in the structure of local defects affects the properties from a "structure-property" perspective.

2.  Two different sizes of carbon materials were used in this work, but the effect of different sizes on dissolved oxygen concentration was not detailed. Also, will size effect of high-purity alumina influence dissolved oxygen concentration.

3.   When the carbon thermal reaction time was 6 hours, why the second phase YAG was only present in the raw material (AlN_C-L)?

4.  A common method used to analyze the conductivity mechanism of ceramics is AC impedance spectroscopy. Please analyze and compare electrical conductivity properties obtained by AC impedance spectroscopy and NMR.

5. There are some English grammar and format errors.
