Abstract (en)

[origin: US2014073729A1] The invention relates to rutile titanium dioxide pigment particles that are capable of reflecting infrared radiation to a high degree and also display pigmenting properties, as well as a method for their manufacture. The particles have a mean particle size of 0.4 to 1.0 mum and are doped with zinc and potassium, but not with aluminium. Preferably, the particles have a compact particle form with a preferred height:width ratio of 1.5:1. The particles are preferably manufactured by the familiar sulphate process for manufacturing titanium dioxide, and are optionally subjected to inorganic and/or organic post-treatment following calcining. Preferably, the rutile titanium dioxide particles are suitable for manufacturing heat-insulating paints, coatings or plastics as well as for instance plasters or paving stones.
