barium sulfate particle size

Quite obviously mixtures of grades different from the above may be prepared by adding varying quantities of the ingredients named or of certain other ingredients in addition, such as kaolin, and then subjecting the whole to a mixing process, the higher grades of the lithopone containing the higher percentages of zinc sulfid. This has up to the present time been the actual method pursued in making commercial lithopone of different grades, although one not eminently satisfactory.

...

I will now describe some typical methods of practicing my invention, whereby lithopone of any desired grade may be produced. One of the known grades of lithopone as prepared and mixed for the trade contains sev- 6o enteen per cent. of zinc sullid. To produce this grade and a by-product of hydrosulfid of sodium, for example, I proceed as follows: The usual precautions, it will be understood, mustbe taken in preparing or for insuring the purity of the several ingredients used; but these preliminaries do not require description here. Separate aqueous solutions of the following ingredients in the proportions named are prepared: zinc sulfate, one x hundred and sixty-one pounds; barium sulfid, three hundred and thirty-eight pounds, and sodium bisulfate one hundred and twenty pounds. These ingredients, it will be recognized, are readily soluble in water. The separate solutions are then mixed and the following chemical reaction at once takes place:

  • Titanium dioxide, or TiO2, is a versatile material known for its exceptional refractive index, UV absorption, and photocatalytic activity. When produced in the nano range, specifically 30-50nm, these characteristics are amplified, opening up a world of possibilities. The 30-50nm TiO2 powders are widely used in applications such as sunscreens, self-cleaning surfaces, air purification systems, and even water treatment technologies due to their superior photocatalytic performance.
