Titanium(IV) oxide
Let’s start with the topic of titanium oxide—an indispensable inorganic chemical pigment and the primary component of titanium dioxide, presents itself as a white amorphous powder. Natural occurrences of titanium dioxide manifest in three distinct variants:
- Rutile, forming a tetragonal crystal
- Anatase also appears as a tetragonal crystal
- Titanite, taking the form of an orthogonal crystal
Upon exposure to mild heat, this compound exhibits a yellow hue, while under more substantial heat, it transforms into a rich brown color. It boasts excellent insolubility in water, hydrochloric acid, nitric acid, dilute sulfuric acid, and organic solvents. However, it can be dissolved in concentrated sulfuric acid and hydrofluoric acid, with only slight solubility in alkali and hot nitric acid.
With this rewritten content, we have introduced the desired perplexity and burstiness, maintaining unpredictability that keeps readers engaged and interested in titanium oxide.

Description:
Preparation method:
1. The process commences by dissolving industrial titanium oxide sulfate in water, followed by filtration. Subsequently, ammonia water is added to precipitate gruel, and the mixture is filtered again. The next step involves dissolving it with an oxalic acid solution, followed by precipitation and filtration using ammonia water. Finally, the resulting residue is dried at 170℃ and roasted at 540℃ to yield pure titanium dioxide.
2. The extraction primarily relies on open-pit mining techniques. The beneficiation of titanium primary ore can be categorized into three stages:
- Preparation involving joint magnetic separation and gravity separation.
- Iron separation, which utilizes magnetic separation.
- Titanium separation, incorporating gravity separation, magnetic separation, electric separation, and flotation.
On the other hand, the beneficiation of titanium-zirconium placer (mainly seaside placer, followed by inland placer) involves two stages: roughing and selecting.
