Beim Chlorid-Verfahren wird Rutil oder TiO2-Schlacke bei 800–1200 °C mit Koks und Chlor zu Titantetrachlorid umgesetzt. Nach Reinigung durch Destillation wird TiCl4-Dampf mit Sauerstoff zu Titandioxid und Chlorgas verbrannt (1000–1400 °C): Titantetrachlorid wird auch bei der Titanherstellung verwendet. Siehe auch: Kroll-Prozess (de) The chloride process is used to separate titanium from its ores. The goal of the process is to win high purity titanium dioxide from ores such as ilmenite (FeTiO3) and rutile (TiO2). The strategy exploits the volatility of TiCl4, which is readily purified and converted to the dioxide. Millions of tons of TiO2 are produced annually by this process, mainly for use as white pigments. The chloride process has largely displaced the older sulfate process, which relies on hot sulfuric acid to extract iron and other impurities from ores.. (en) 氯化法是指用來從含有至少百分之九十的二氧化鈦的礦石中純化出二氧化鈦的方法。在此過程中，原料會和碳在氯氣中加熱到900度，产物是四氯化鈦和碳氧化物。接著，利用蒸餾來純化出四氯化鈦，再加入氧來將其氧化，最後便可以得到純化了的二氧化鈦了。 克羅爾法（Kroll process）是個和氯化法有關的技術。在純化出四氯化鈦之後，不將其氧化，反而用鎂來將其还原，以得到金屬鈦。 (zh) |
