Natural potash feldspar was used in an attempt to synthesize leucite crystals. The conditions necessary for synthesizing leucite crystals were examined and the crystal morphology were investigated. In addition, the formation mechanisms of leucite crystals were discussed. When a mixture of Al2(SO4)3: Potash feldspar: K2SO4=3:3:15 was heated at 1100°C for 3 h, 50-60 μm diameter leucite crystals formed. Potash feldspar was stable up to 1000°C by this synthetic method, therefore a heating temperature of 1100°C was needed to form leucite crystals.
