Results combining efforts of different groups on investigation of losses in superconducting radio frequency cavities made of niobium are presented. Peculiarities of such losses and of their remedies are considered for dissipation at high accelerating voltages. The main results of RF tests as well as main experiments conducted via physico-chemical research methods on samples are discussed. The role of different type of defects on losses is presented. The candidate mechanisms for dissipation are considered based on exhibited results. As a conclusion the prediction is made on possible alternative processing steps for improvement of cost, time and safety efficiency of current technological procedures. Keywords:
superconductivity, cavity, niobium, quality factor, surface science.
