White flaky crystals. D3. 012; Melting point 780 ℃. Soluble in hot water, micro-soluble in cold water and inorganic acid, insoluble in ammonia. In the air heated to more than 500 deg C, the gradual oxidation of titanium dioxide. Non-combustible. Toxic fluoride gas is released by thermal decomposition.
hydrofluoric acid reacts with metatitanic acid to form fluorotitanate acid, which is then neutralized with potassium hydroxide.
used as a catalyst for the synthesis of polypropylene. Also used for aluminum, titanium and boron alloy manufacturing, aluminum processing and light metal smelting additives.
It has a stimulating effect on the skin and mucosa. Staff should be protected. If the skin and eyes are touched, they should be immediately rinsed with plenty of flowing water. Store in a cool, ventilated warehouse. Keep away from fire and heat source. Mixing with oxidant and edible chemicals is strictly prohibited.
