Brief description
Micrograph showing the complex chemical reactions which arise at fibre-matrix interfaces in a fibre reinforced magnesium aluminosilicate ceramic subjected to oxidation
Keywords
ceramic Link to MATTER Glossary entry for ceramic, fibre Link to MATTER Glossary entry for fibre, magnesium aluminosilicate
Categories
Ceramic
System
SiC fibre-reinforced magnesium aluminosilicate
Composition
Not specified
Standard codes
Reaction
Processing
The fibres are drawn and infiltrated with a slurry consisting of a powdered matrix in an organic binder and water.. The mixture is hot pressed to give a dense composite.
Applications
Sample preparation
Technique
Bright-field TEM
Length bar
300 nm
Further information
An approximately 1.2 micrometre thick interfacial region is seen between the matrix and the fibre. I1-4 are four distinct interlayers with different compositions within this region.
