Bubble nucleating and porosity were improved by adding lignin granule, and cell size of the polyurethane foam was decreased. Not only physical property but also thermal property of the material were enhanced. Compared with soft polyurethane foam, tensile strength of lignin reticulated polyurethane foam was raised by 140% at most which lignin content was 5%, and the heat-degradation temperature at the first stage was 50℃ more than soft polyurethane foam which lignin content was 10%. There had been a great improvement in heat resistance of the material. It was showed that weight of biological film reached to 10000 mg/L and 12100 mg/L when the lignin content of the polyurethane foams was 5% and 8% respectively via 30-day biofilm formation testing.

Extensive research has been conducted to find ways of reducing such porosity; however, it is difficult if not impossible to eliminate completely, and die castings often are lower in strength than low-pressure or gravity-fed permanent mold castings, which are more sound in spite of slower cooling.

大量的研究工作旨在降低这一气孔率，可是实际上要想完全消除是相当困难的，并且压模铸造铸件的强度经常不及低压和重力铸造获得的铸件，尽管后两种方式的冷却速率教慢，但是其可靠性相对较高。

Results show that the mullite grogs can be gained by the method at 1700℃ as long as the control of the chemical composition of ingredients(content of Al2O3 and ratio of Al2O3/ SiO2 ,etc.) with apparent porosity＜2.5% and bulk density≥2.75g/cm3; the heating process can be divided three stages, which are formation of primary mullite, secondary mullitization stage and liquid phase sintering stage.Key words bauxite, coal gangue, mullite grogs
