1、 Overview

Molecular formula K2CO3, molecular weight 138.21.

Properties: white powder or fine grain crystal (heavy). Specific gravity 2.428, melting point 891 ℃. It is easily soluble in water and its aqueous solution is alkaline. It has strong hygroscopicity. If it is exposed to the air for a long time, it will absorb water and carbon dioxide in the air and generate potassium bicarbonate.

IIPurpose:

Potassium carbonate is widely used in the chemical industry for the manufacture of optical glass and welding electrodes.

In the PCB industry, potassium carbonate is the main raw material for the production of commercial developers. It is most commonly used in the development of photosensitive inks, especially high-end solder resist inks.
