Scour media for titanium dioxide production |
摘要 |
Anatase titanium dioxide pigment calcined to a crush strength and density meeting the requirements for an acceptable scour medium is effectively utilized as a scour medium in the chloride process for producing rutile titanium dioxide. The calcining process converts a portion of the anatase pigment to rutile. This calcined anatase can, consequently, be utilized as a scour medium in the chloride process for producing rutile titanium dioxide. The calcined anatase is not a contaminant to the process for producing rutile titanium dioxide. Thus, relatively inexpensive anatase can be converted into a rutile scour medium that can be processed into pigment.
