摘要:
Fused oxide type glasses produced by flame hydrolysis are described. These glasses are composed of P.sub.2 O.sub.5 and, optionally, SiO.sub.2. P.sub.2 O.sub.5 is present in an amount of at least 2% by weight.
摘要:
Biocidal glass materials are prepared from a mixture of boric oxide, aluminum oxide and cupric oxide in powdered form. After fusing the powder into glass, the glass is ground and deposited in a marine paint composition to provide a paint decomposition rate of 20 micrograms per hour in seawater.
