Corrosion resistance of soda lime silica glass bottles manufactured in Egypt

ABSTRACT

The different types of bottles manufactured at El-Nasr Glass and Crystal Co., Mostorod Factory, were tested to determine their class according to the USP. The corrosion resistance of such bottles towards the attack of water, HCl, NaOH and methyl and ethyl alcohols at different temperatures and times was also studied. The results obtained showed that amber glass bottles belong to class III, whereas, green and colorless bottles belong to the NP class according to the USP. The difference in their corrosion resistance was related to the lower alkali content of amber bottles compared to colorless and green bottles. The results of the effects of the different aqueous solutions, as well as temperature and time of attack, were similar to that published on glasses of similar chemical composition
