Allochroic Silicagel AR 500g factory price reagent cas 7778-80-5 1. In animal husbandry, silica gel 300 was used to prepare cholinoid chloride powder to improve the loose degree of vitamin A, D, E, B2 in micro-particles. 2. Used as a stationary phase for gas chromatography and liquid chromatography. It is also used for dehydration and purification of gases and liquids.The main component of color-changing silica gel is cobalt chloride, which is highly toxic and has a strong adsorption effect on water vapor in the air. At the same time, it can display different colors by changing the amount of cobalt chloride crystal water contained. The blue color before moisture absorption gradually turns into light red with the increase of moisture absorption.color: blue colorblueAppearanceBeaded particlesTemperature resistance750 (ºC)ViscosityNoneMain purposeelectronic moisture-proof, color indicator
