WebThe optimised plasma deposition of phospho-silicate glass at a temperature of 300°C with a low phosphorous concentration (<10 wt% P) prevents surface leakage and does not show plasma damage. Publication: Applied Surface Science Pub Date: May 1993 DOI: 10.1016/0169-4332 (93)90518-G Bibcode: 1993ApSS...69..277R WebAbstract Mutual relation between thermal activity and biochemical activity of the phospho-silicate glasses which are used as controlled rate release fertilisers and bioglasses for medical applications, has been observed. Analysis of the local atomic interactions in the structure of glass is used to explain this relation. docker checksum failed
