The research on calcium sulfate whiskers started relatively late in China, starting at the end of the 1980s; however, over the years, research has also come a long way. Liwu et al. took gypsum dihydrate with calcium sulfate content more than 95% as raw material. The ratio of gypsum to water was 1:5-20, the hydrothermal reaction temperature ...

The FTIR spectra confirmed the presence of ammonium salts in the interlayer space as C-H stretching bands (3100-2800 cm-1) were found. Also the vibrations of kaolinite OH hydroxyls were altered in 3700-3600 cm-1 region. The intercalation of AzBz shifted the basal spacing of MBTA and MBC16A to 23.1 and ~50.8, respectively. ... oil reservoirs ...

Two methods were used for the separation of the iron from the nickel and cobalt—one by precipitation of the iron as basic acetate, and the other by precipitation with carbonate of baryta in the presence of an excess of chloride of ammonium; but in neither case was the separation perfected on the first precipitation, and traces of nickel ...

In general, commercial production of the Cavendish variety gives yields ranging 40-60 Mg/ha FW in other regions (India and China), while small producers report yields of about 30 Mg/ha FW. In the Philippines, actual yields are low, with varieties such as Saba (cooking—ABB) and Lakatan (dessert—AAA), yielding 11-20 Mg/ha FW.

Ammonium exists in equilibrium with ammonia gas and, at a pH between 7.5 and 8.0, 10 percent of the nitrogen will be in the gaseous ammonia form [56] . Volatilization of significant quantities of ammonia requires not only a high pH but also considerable air-water contact [121], Therefore, the mecha- nism is not expected to provide significant ...
