A varięty of techniques was used to study the effects of silver and silver oxide additions on the environmental stability and mechanical durability of superconductors. The extent of the environmental degradation was examined using X-ray diffraction and optical microscopy., Vickers hardness was measured on bulk samples and thick films were tested for adherence by a scratch test. Results on the bulk samples demonstrate an improvement in both environmental stability and Vickers hardness with increasing silver addition. Screen-printed films were overfired and some Y2BaCuO5 phase formed. For this reason, results obtained from these samples may not reflect the true behavior of YBa2Cu3O7-x films.
