Popis: The effect of microcracks arising during abrasive treatment on the short-term and long-term strength of specimens prepared from magnesium-aluminum ferrite with a spinel structure has been studied. With the aim of orientating surface microcracks grinding of specimens has been carried out parallel, perpendicular, and at an angle of 45° to their axes; testing was performed by a four-point bending scheme. It has been shown that in order to improve the reliability of ceramic articles whose production process includes abrasive treatment a scheme should considered for applying the maximum tensile stresses during operation of an article and orientation of microcracks contributed by the abrasive treatment in relation to these stresses.
