Chloride vs Sulphate Titanium Dioxide

Chloride and sulphate describe manufacturing routes for titanium dioxide pigment. The process name is useful sourcing context, but it does not prove that a grade will meet a coating, plastic or ink target. Compare the exact grade, documented limits and customer test results.

Scope: This is general guidance; product-specific facts require an approved exact-grade source.

What the process names mean

EPA process descriptions show chloride production converting titanium-bearing feedstock to titanium tetrachloride before oxidation, while the sulphate route digests feedstock in sulphuric acid and later hydrolyses and calcines the titanium intermediate. Real plants and finishing steps vary.

Buyer checklist

• Confirm process only from an official product or producer record.
• Review exact-grade surface treatment and test methods when documented.
• Compare application performance through controlled trials.
• Do not use process route as a substitute for a specification.
