Embodiment 1
[0035] 1. A kind of iron-rich nickel slag glass-ceramics:
[0036] The composition of the iron-rich nickel slag glass ceramics: nickel slag 90.27±0.02wt%, KNO 3 2.11±0.01wt%, Sb 2 o 3 7.62±0.01wt%, the crystallization temperature is 860°C, and the crystallization time is 10min. The flexural strength, acid resistance, alkali resistance, density, water absorption, etc. of the iron-nickel slag glass-ceramics were tested respectively, and compared with the national standard.
[0037] See Sample 1 in Attached Table 1 for specific results.
[0038] It can be seen from Table 1 that the iron-rich nickel slag glass-ceramics has good corrosion resistance, especially alkali resistance, and the quality change is small after being corroded by acid-base solution for 24 hours; the flexural strength has reached 56.87MPa, and all indicators meet the requirements of the national standard .
