Summary: | The invention discloses a preparation method of potassium hexatitanate whiskers for a friction material, which comprises the following steps: taking K2CO3 and TiO2 as raw materials, and taking KCl and K2O-MoO3 as fluxing agents; the preparation method specifically comprises the following steps: S1, mixing K2CO3, TiO2 and KCl according to a certain proportion, and then carrying out heat preservation in a corundum crucible furnace at 660-680 DEG C for 1-2 hours; s2, K2O-MoO3 is slowly added into the crucible furnace, meanwhile, the furnace temperature is increased to 920-980 DEG C, and heat preservation is conducted for 2-3 h; and S3, cooling the furnace temperature to room temperature, then adding the obtained solid product into deionized water, controlling the solid-to-liquid ratio and temperature, and controlling the generation time of the potassium hexatitanate whisker. According to the method, K2CO3 decomposition and K2O burning loss are promoted through KCl, a potassium source is supplemented through K2O- |
