preparation Embodiment 1
[0076] The kaolin A was calcined at 750° C. for 2 hours to obtain a calcined material (referred to as the first calcined material), and 168 g (dry basis, the same below) of the calcined material was added with decationized water (pH=3.1, the same below) and stirred to prepare. A slurry with a solid content of 25% by weight was added, 500 g of hydrochloric acid, 100 g of oxalic acid, 3.11 g of diammonium hydrogen phosphate, and 3.00 g of ferric chloride were added with a concentration of 1 mol / L, and the temperature was raised to 70 ° C, stirred at 70 ° C for 1 hour, and then filtered to remove Mother liquor, the filter cake is dried to obtain the first step product; the first step product 120g is roasted at 750 DEG C for 2 hours to obtain roasting material (called the second roasting material), 100g (dry basis, the same below) the second roasting material Add decationized water and stir to obtain a slurry with a solid content of 25 wt %, add 200 g of hydrochloric acid, 50 g of ...
