The most typical business glass styles comprise both of those alkali and alkaline earth ions (commonly sodium and calcium), for less complicated processing and gratifying corrosion resistance.[127] Corrosion resistance of glass could be improved by dealkalization, removal of your alkali ions from the glass surface[128] by response with sulfur or fluorine compounds.[129] Presence of alkaline metal ions has also detrimental effect to the decline tangent of the glass,[130] and to its electrical resistance; glass created for electronics (sealing, vacuum tubes, lamps ...) really need to choose this in account.
