Reference Mixture and Cellulose

The maximum burning rate of the reference material was achieved with barium nitrate mixed with dried cellulose in the proportion 40 to 60 (w/w).

Test article with Cellulose

 

The test article was mixed with dried cellulose in various ratios and tested as described in the experimental section above. The results of the different mixtures are reported in Table 2.
