1. prepare a method for calcium metatitanate, it is characterized in that concrete steps comprise as follows:

  • (1) first calcium chloride hydrate and titanium dioxide powder are mixed according to mass ratio 1;

    1 ~ 6;

    1 and obtain mixture, then mixture is made type at the pressure of 2 ~ 15Mpa and obtain molding materials;

    (2) molding materials that step (1) obtains is sintered in atmosphere, control temperature rise rate be 5 ~ 20 DEG C/min rise to temperature be 800 ~ 1100 DEG C insulation 30 ~ 180min obtain sintered product;

    (3) sintered product step (2) obtained is hydrochloric acid soln leaching 10 ~ 30min that 15;

    1 ~ 40;

    1ml/g adds that concentration is 3wt% ~ 5wt% according to liquid-solid ratio, then the solid deionized water obtained after solid-liquor separation cleans to can'"'"'t check chlorion repeatedly, can prepare calcium metatitanate by after the solid drying after washing.
