Problems solved by technology

High calcination temperature, long calcination time and complicated procedures are the main reasons for high cost
General Choy et al. and Bao et al. [13，24-26] The study found that K 2 Ti 6 o 13 The synthesis of w needs to be calcined at a high temperature of about 1100 °C, but the high calcination temperature directly leads to high energy consumption, high potassium loss and rapid equipment corrosion loss under alkaline synthesis conditions
