Pressure Induced Decomposition of KHSO4.

Pressure-induced decomposition of indium hydroxide.

A static pressure-induced decomposition of indium hydroxide into metallic indium that takes place at ambient temperature is reported. The lattice parameter of c-In(OH)(3) decreased upon compression from 7.977(2) to approximately 7.45 A at 34 GPa, corresponding to a decrease in specific volume of approximately 18%. Fitting the second-order Birch-Murnaghan equation of state to the obtained compre...

Structural changes and pressure-induced chemical decomposition of boric acid

X-ray powder diffraction studies along with complementary Raman and infrared spectroscopy measurements disclosed the pressure-induced chemical decomposition of boric acid, H3BO3. The layered triclinic structure of H3BO3 suffers a highly anisotropic compression associated to a strong reduction of the interlayer spacing. The starting structure becomes unstable at about 2 GPa and decomposes on a c...

Effect of CO2 Partial Pressure on the Thermal Decomposition Kinetics of Zinc Carbonate Hydroxide (TECHNICAL NOTE)

In this work, the effect of carbon dioxide partial pressure on the calcination kinetics of high purity zinc carbonate hydroxide has been studied. Non-isothermal analysis has been performed on samples at different CO2 partial pressures by TGA and DTA. It has been found that the calcination behaviour of this material corresponds to the shrinking core model and the reaction mechanism is phase boun...
