In part I of this study, the dip-coat processing of mullite/gadolinium silicate (Gd 2 SiO 5 ) environmental barrier coatings (EBCs) applied on ฮฑ-SiC and SN282โข Si 3 N 4 through alcohol based and sol based slurries was presented. Here, the performance of selected EBCs by evaluating their oxidation re
## Chemical vapour deposition of Si3N 4 by pyrolysis (1200-1275ยฐC) of tetramethylsilane-ammonia-hydrogen mixtures (N:Si = 10) was used to protect reaction-bonded silicon nitride substrates against internal oxidation at 1000-1350 ยฐC. The results reveal the existence of a critical thickness (6 gm)
