Barium Carbonate AR is an inorganic compound, which is widely demanded for its purity, accurate composition and effectiveness. Precisely formulated, using pure ingredients, these chemicals are delivered in safe and tamper proof packaging so ensure damage-free delivery. It is used in ceramic industry as a constituent in glazes.
he kinetics of decomposition of barium carbonate in nitrogen and in vacuo have been established using isothermal weight loss measurements. ... The observed activation energy for the decomposition of barium carbonate was _ 60 kcal/mole in the temperature range from 800°C to 1000oC.
