摘要： In this patent, reaction sintering was used to prepare translucent strontium barium niobate ceramics (SrxBa1-xNb2O6, x=0.2-0.7). High purity powders of strontium carbonate (SrCO3) and barium carbonate (BaCO3) were mixed with niobium oxide (Nb2O5), respectively, at the same mole using ball milling. The mixed powders were dried and ground by a mortar. Thereafter, they were calcined at 800-1050° C. for 1-4 h in air to form strontium niobate (SrNb2O6) and Barium niobate (BaNb2O6), respectively. Precursor powders of strontium niobate (SrNb2O6) and barium niobate (BaNb2O6) were mixed in appropriate ratios and pressed. Compacts were reaction-sintered in a temperature range of 1300 to 1320° C. in O2 and then heat-treated in a temperature range of 1260 to 1275° C. in O2. We also propose the related basic principles and microstructures.

摘要： Process and apparatus for regenerating spent acid liquor includes a primary roasting furnace for evaporating a substantial portion of the liquid from the spent acid to produce acid vapors and partially roasted metal salts. The partially roasted metal salts are transferred to a secondary roasting chamber where the acids adhering to the surface of the metal salts is vaporized and the metal salts are oxidized. The acid vapors from the primary roasting furnace are then transferred to an absorption column to regenerate the acid. The primary roasting furnace is operated at a different temperature from the secondary roasting chamber and has different retention times for the metal salts. The secondary roasting chamber includes a raking device to mix and convey the metal salts during the secondary roasting step to produce a uniformly roasted metal oxide.

摘要： A method of manufacturing micro-particulated hydrated lime slurries includes the steps of blending hydrated lime and water to form a mixture, mixing the hydrated lime and water mixture under high shear to form a slurry, transferring the hydrated lime and water slurry to a storage container, and adjusting the percent weight solids of the hydrated lime and water slurry to a predetermined weight solids content. Mixing the hydrated lime and water mixture under high shear can include mixing with a high shear disperser and/or with a high shear rotor/stator mixer. The resultant slurry includes hydrated lime particles with a median particle size of about 6 micrometers or less.
