Patent ID: 8182825

Claim:
Memory energy memory ceramics granules prepared by a process comprising: (1) preparing evenly-mixed mixture of silicon oxide (30-60 wt %), aluminum oxide (25-40 wt %), sodium oxide (0.05-1.5 wt %), potassium oxide (0.5-2 wt %), magnesium oxide (0.5-1 wt %), calcium oxide (0.5-1 wt %), titanium oxide (0.5-1 wt %), ferric oxide (2.5-5 wt %), manganese oxide (0.01-0.05 wt %), and zinc oxide (0.005-0.05 wt %); (2) removing impurities and calcining/drying for 12 hours at 1100-1250° C.; (3) sieving out the sintering materials with high ratio of heavy metals; (4) grinding it to powder; (5) oxidizing the powder and mixing it with argil as 70:30 wt %; and (6) making granules.
