Blanc de Comines, 27 per cent zinc sulphide, 70.5 per cent barium sulphate, 2.5 per cent zinc carbonate.
The ingredient in question? Titanium dioxide.
1. Purity The purity of barium sulphate is essential, especially in applications such as pharmaceuticals. Suppliers should provide certifications stating the purity levels and any presence of impurities or contaminants.
In addition to controlling the reaction conditions, it is also important to carefully monitor the precipitation process to ensure that the desired precipitation percentage is achieved. This can be done through various analytical techniques, such as X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy, which can provide valuable insights into the particle size distribution, crystallinity, and purity of the titanium dioxide product.
