Sažetak
Flexural strength,  fs, of cold isostatically pressed alumina ceramics, (CIP)-Al2O3, with a purity of 99.8 % was determined by the three - point bend test. The flexural strength was found to range from 266.7 to 372.2 MPa. It is well known that the measured fracture of brittle ceramics shows large variability. Therefore, the probabilistic characteristics of the flexural strength were analysed by a two-parameter Weibull distribution function, with a scale parameter,  0, and the Weibull modulus, m. These parameters were determined by the linear regression method for  fs data measured. It was found that the measured flexural strength,  fs, of alumina ceramics follows the Weibull distribution.
