From a stability standpoint, lithopone, a fusion of zinc sulfide and artificially precipitated barite, is non-toxic and exhibits resilience to mild lyes and acids. However, it is incompatible with colors containing copper. Despite its strong covering power in oil, lithopone’s drying capabilities are notably limited, posing potential issues for artists. Notably, early experimentation with lithopone-based grounds instead of zinc white resulted in undesirable darkening, although this blackness receded upon drying. This unpredictable behavior has sparked debate among scientific communities, emphasizing the need for further exploration and understanding of this pigment.

In the world of industrial processing and manufacturing, the term 1250 mesh holds significant importance, particularly in the field of powder and particle size reduction. This refers to a screen or sieve with a very fine aperture, capable of separating particles down to an incredibly minute level. The demand for 1250 mesh products is driven by various industries such as pharmaceuticals, cosmetics, food processing, and mineral refining, among others, where ultra-fine particle sizes are essential for optimal performance.

  • Titanium dioxide is a key ingredient in many products, including paint, sunscreen, and food coloring. As a result, there is a high demand for this versatile compound, leading to the need for reliable suppliers who can provide high-quality titanium dioxide.
  • Lithopone 28-30%, also known as B301 and B311, is a white pigment that has been widely used in various industries due to its excellent properties such as high brightness, good weather resistance, and chemical stability. This pigment is primarily composed of zinc sulfide (ZnS) and barium sulfate (BaSO4), which are combined in a specific ratio to achieve the desired color and performance.
  • titanium oxide and 2 per cent' sulphuric acidand 63 per cent water, are slowly added to a solution containing 1050 pounds of barium sulphide, held in a large cylindrical tank, provided with a rotary agitation :capable of producing rapid agitation. The mass isthus v rapidly agitated, and the 2 per cent of sulphuric acid contained in the titanium acid cake reacts with a small portion of the barium sulphide. This reaction may be represented by the following equation TiO H 80 The free sulphuric acid of the titanium acid cake is neutralized by thebarium sul-' phide solution, forming barium sulphate and hydrogen sulphide, as indicated by the above equation. As the sulphuric acid is present only in a small percentage, the major porltiion of the barium sulphide remains as suc very fine colloidal suspension. The barium sulphate produced is also very fine, and the presence of this. very fine barium sulphate in suspension, and also of the very fine colloidal titanium oxide, is believed to be the explanation of the great improvement in the properties of the finished lithopone.
