Manufacture and mechanical properties of magnesium potassium titanate short fiber/glass composite

We generated a composite of short magnesium potassium titanate fibers (K2MgTi7O16) and glass by calcining hydrated potassium tetratitanate fibers/non-swelling synthetic fluorine mica with a mass ratio of 7 : 3 at calcination temperatures of 1000°C or higher for 1 h. The sintered density and bending strength of the K2MgTi7O16 obtained was 79% and 27 MPa, respectively, at a calcination temperature of 1100°C. We also isolated magnesium potassium titanate fibers approximately 3 μm in diameter by treatment with a 5% fluoric acid solution for 30 min.
