The effect of hydrophobic additive on the seed precipitation from sodium aluminate solution was studied by adding fatty acid and heneicosane at different proportions. The results show that when the mass fraction of fatty acid is in the range of 32%-49% and the additive concentration in sodium aluminate solution is 150×10-6 g/L, the rate of precipitation increases, but the particle size of Al3 and Al2O3 reduces.

摘 要：研究了疏水性添加剂脂肪酸类阴离子表面活性剂与21-碳烷不同配比对铝酸钠溶液分解产生氢氧化铝和氧化铝的粒度、强度及分解率的影响，考察了产物Al3和Al2O3的强度和粒度之间的关系，探讨了添加剂影响铝酸钠溶液晶种分解的相关机理。

The experimental results showed that SiC ultrafine powder was synthesized at 1500℃for 120 minutes by used rare earth lanthanum as additive. Its primary particle size was about 100nm and aggregated particle size was about 360nm and the particle shape was regulation, non-aggregation and well dispersibility. While the rare earth ceria used as the additive, SiC ultrafine powder was synthesized at 1500℃for 150 minutes but the particle shape was irregulation and seriously agglomerated and had numerous crystal whiskers.

The stabilities of the extract from sanguisorba under different pH, light, heat, ultraviolet ray, oxidant, reducing agent and additive agents were studied. It was indicated the products could widely used in the condition of weak acid or neutral, while they were not stable to heat and light, so they should be used without light and at low temperature. The products had a strong ability to withstand ultraviolet ray. They could easily be oxidized and degraded by oxidant while they were not easily affected by reducing agent and were almost not affected by additive agents. The extract from the stem of sanguisorba was analyzed by UV and FTIR, showing that the structures of the active components were not changed during ultrasonic wave extracting.
