The most typical indicating silica gel is blue silica gel and orange silica gel. Blue silica gel is also known as self indicating silica gel as it is prepared by impregnating white silica gel with cobalt chloride present in a concentration of 0.5 to 1% weight for weight.
The gel is mainly used for indicating desiccant’s absorbing degree and environmental relative humidity by being mixed with common silica gel in proportion.
One of the principal reasons for the use of Indicating silica gel is its ability to release adsorbed moisture when heated to a temperature of over 100℃. This means it can recovered and used again.
