WO3, an interlayer compound prepared by J. W. Johnson (1981) using yellow tungstic oxide hydrate. Suspension of white powdery tungstic acid in anhydrous pyridine yields on standing for 2 wk whiteHW4O13.3H2O. IR and DTA studies revealed the connection between that pyridine polytungstate and white powdery tungstic acid (microcryst.), whose composition may thereby be assigned as H2W4O13.nH2O.

WO3。粉状白钨酸在无水吡啶中放置两周后可得到另一种化学式为(C5H5NH)HW4O13.3H2O的吡啶化合物，经IR和DTA研究可初步说明该化合物与粉状白钨酸之间的联系，并因此推测白钨酸的组成可能为H2W4O13.nH2O。

SO3 is fixed in ashes at 850~900℃, and it exists in Ⅱ-CaSO4 and has different solubility with the natural anhydrite and the plaster calcined at 400℃. It is the first time to prove that the particles of f-CaO is coated withⅡ-CaSO4 by investigating the process of forming f-CaO, the microstructure, spathic type and optic parameter and the hydrating process.

Secondly, spinnability of SF dope was studied. The results indicated that the higher concentration of the dope and the less content of H2O would result in the better spinnability. And higher concentration of the dope had good spinnability whether the dissolution system containing minim EDTA or not. Pure EtOH and LiBr/EtOH (40/60, w/w) were used as solvent, to which minim EDTA was added. Then certain degummed SF was dissolved in the above mixed solvents to prepare the dope (21.7wt%) containing minim EDTA or not, respectively.
