Alkali Metals | Encyclopedia.com

Alkali metals also react with the oxygen in the air to give an oxide, peroxide, or superoxide, depending on the metal. Alkali metals usually form ions with a positive (+ 1) charge, and are so reactive as elements that virtually all occur in nature only in compound form.

The flow rates for each channel/tube were determined through a basic calibration of the pump speed versus the total liquid dispensed from each tube. The pH indicator and alkali ratios were controlled using a 4-to-1 multi-way valve which was connected to a bank of NaOH solutions, each with a different concentration from 10 to 100 μM.

Damage and performance loss may occur by various mechanisms. Alkali species may simply form deposits in the turbine (fouling), inhibiting air flow, reducing efficiency, and eventually stalling the turbine. Many alkali compounds are liquids at these temperatures (Stringer 1987) or may form low-melting mixtures with other materials (Misra 1992b).

Poor alkali resistance Problems | Dulux

Poor alkali resistance occurs when solvent-based coatings are applied to new masonry that has not cured for a full year. Fresh masonry is likely to contain lime, which is very alkaline. Until the lime has a chance to react with carbon dioxide from the air, the alkalinity of the masonry remains so high that it can attack the integrity of the ...
