中文摘要	Glass-ceramics were prepared from phosphorus slag as the main raw material by sintering method. The factors influencing the sintering behavior were investigated by orthogonal test and X-ray diffraction. The results show that the dominant factor is sintering temperature, the second is P/sub 2/O/sub 5/ content, the third is the particle size, and the last is the holding time. P/sub 2/O/sub 5/ had a significant effect on the sintering behavior when the other three influential factors were invariable. When the P/sub 2/O/sub 5/ content (mass fraction, the same below) was less than 1.8%, beta -CaSiO/sub 3/ was the main crystalline phase at below 1 000 degrees C and the surface of the glass-ceramics was not smooth. When the P/sub 2/O/sub 5/ content was more than 3.6%, the required sintering temperature was increased to 1 100 degrees C; meanwhile, the required holding time was dramatically prolonged. In this case, Na/sub 2/Ca/sub 2/Si/sub 3/O/sub 9/ became mainly crystalline and the surface of the glass-ceramics was not smooth. As a result, the preferential P/sub 2/O/sub 5/ content was in the range of 1.8%-3.6%, sintering temperature was 1 000-1 050 degrees C, sintering time was 60 min, and glass-ceramics with a smooth and flat surface could be obtained.
