When 1% zirconia (ZrO2) was added in glass the extraction of alkalis suddenly reduced from 0.
Chemical durability showed that with gradual substitution of ZrO2 in glass, the resistance of the glass to chemical attack was increased and gradually reduced the extraction of alkali to a least value near to zero.
Water usually attacks much less vigorously than alkali but attack of water quickly becomes the attack of alkali as alkali is extracted from the glass into the solution to the take part in the reaction.
Evolved magmas can have lower viscosities than intermediate ones because of increased alkalis and volatile contents.
Tholeiites form at lower pressures than alkali basalts, from higher percentages of decompression melting.
Plagioclase dramatically removes Sr at intermediate stages and alkali feldspars sequester Ba and Rb as late-stage trachytes and phonolites form in alkaline magmas.
He notes that certain atomic interactions have been calculated exactly for hydrogen but can only be approximated for the more complex alkalis.
In 1995, a team using the alkali metal rubidium raced past them to make the first sample of the remarkable form of matter (SN: 7/15/95, p.
com/research/53s6nm/analyzing_the_alka) has announced the addition of the "Analyzing the Alkalis & Chlorine Market in US 2012" report to their offering.
The economic recession has had a negative impact on many of the industries that use alkalis and chlorine, such as chemicals, plastics and glass.
Alkali activation is the process of aluminosilicates dissolution in strongly alkaline solution, with a subsequent formation of aluminosilicate networks composed of Al[O.
One of the first studies of alkali activated fly ash concerned the synthesis of zeolites.
