摘要: Slit-island analysis (SIA) has been successfully used to measure the fractal dimensional increment (D*) of fracture surfaces. The toughness in brittle ceramics is related dimension. However, measurement technique may affect determined D* values. purpose this study was determine contour angle at which a valid dimension could be obtained using SIA method for baria silicate glass-ceramic and zinc selenide ceramic. Two specimens each material were duplicated following angles: 0°, 3°, 5°, 7°, 22°, 90°. After polishing 1 μm alumina slurry, coastlines photographed arranged collage. coastline analyzed Richardson technique. Results showed that sensitive since decreases with increasing both materials.
