Ceramic Materials Analysis
TMA:
-
Measure thermal expansion rates as a function of temperature
-
Measure shrinkage as a function of firing a green ceramic to 800° C
TGA:
-
Measure the change of weight as a function of temperature to determine the rate of binder loss with temperature
-
Measure outgassing of ceramic upon heating
-
Measure the weight of any organic binder
SEM and optical microscopy:
-
Imaging of fracture surfaces to determine particle sizes and see residues of organic binders
-
Cross section analysis to evaluate cracks and voids
-
Examine surfaces for cracks and voids
Profilometry:
-
Determine surface roughness of cast or machined surfaces
XPS or ESCA Analysis:
-
Analysis of surface contamination of ceramic pre-cursor powders or particles
-
Analysis of surface contamination of fired ceramics
-
Check chemistry of binders
-
Determine surface chemistry of raw material particles prior to use for water or impurities
-
Analysis of fracture surface chemistry to determine binder and pre-sintered particle surface chemistry effects on fracture plane
-
Degradation effects upon ceramic such as moisture on BN or Al2O3
-
Precise quantitative chemical phase identifications
Infrared Spectroscopy (FTIR) Analysis:
-
Check the organic binder chemistry of a ceramic paste
-
Identify organic contaminants after use
-
Identify carbonates, water, phosphates, sulfates, and nitrates in inorganic pre-cursor particles
RGA Mass Spectroscopy:
-
Identify outgassing products such as boric acids from BN caused by hydration
-
Identify and measure contaminants picked up while in use or storage
