The prices in India settled at 2888 USD/MT in September, indicating a decrease. Throughout the quarter, demand in India varied in a limited range, particularly in the latter half of September as a result of the second round of lockdown in numerous sections of the nation.

THE OBSCURE HISTORY OF A UBIQUITOUS PIGMENT: PHOSPHORESCENT LITHOPONE AND ITS APPEARANCE ON DRAWINGS BY JOHN LA FARGE

Le lithopone, blanc de lithopone ou blanc de Comines est un pigment blanc composé d'un mélange de sulfure de zinc et de sulfate de baryum, généralement en proportions équimolaires.

Relative Density Among commonly used white pigments, lithopone has the smallest relative density. Among white pigments of the same mass, titanium dioxide has the largest surface area and the highest pigment volume.

There are two primary forms of titanium dioxide commercially available: anatase and rutile. The rutile form is typically used in sunscreens due to its superior ability to handle UV rays and stability in the presence of UV light. The anatase form is typically used in other types of products, such as paint. Another plus of the rutile form is that its UVA protection extends past 400 nanometers, which is the upper limit of UVA.
