Crystallisation of Barium Chromate
… of low solubility materials were studied, Barium chromate being chosen as a typical one. The increase in solubility in acid solution was examined. Also the solubility of Barium chromate in the Presence of other compounds (Urea, complexing agents) was Studied. Conditions of supersaturation …

An Investigation of the Reaction of Ozone with Barium Peroxide and Barium Hydroxide
… at room temperature. |Sepia brown compounds of barium and calcium have also been reported when these metals were reacted with ozone while being cooled with dry ice and acetone. There has been no work done on the composition of these compounds because they decompose as soon as they are removed …

Photoionization of laser excited barium
… photoionization of the 6s6p ¹P excited state of barium were measured over the range 420 - 368 nm. This range includes threshold as well as numerous autoionizing resonances resulting from excitation to discrete states embedded in the ionization continuum. The experiments were motivated by a need …

Barium Titanate-Based Magnetoelectric Nanocomposites
Barium Titanate (BaTiO3 or BTO) has attracted an ever increasing research interest because of its wide range of potential applications. Nano-sized or nanostructured BTO has found applications in new, useful smart devices, such as sensors and piezoelectric devices. Not only limited to one material, …

Growth Rate of Barium Chromate Crystals.
The crystallisation of barium chromate was investigated with theobjective of producing crystals of 10-4m in size instead of thecommercially available size of 2 x 10--6m. This was achieved by themethod of controlled homogeneous precipitation from solutions oflow pH. However, this was not an optimum …

Barocaloric effects in barium-dicalcium propionate salts
… contribute to environmental damage. Should barium dicalcium organic salts show persistent entropy changes under pressure that are reversible, they may serve as environmentally friendly solid-state barocaloric cooling materials. In this thesis, I synthesised barium dicalcium propionate and …

Barium carbonate treatment of sulfuric acid wastewater
… sulfuric acid wastewater through the addition of barium carbonate and the formation of a barium sulfate precipitant were investigated. Optimization of barium carbonate dosage, reaction time and mixing conditions was accomplished for each method prior to evaluating the treatability of the reaction …
