Titanium dioxide purity can be determined using various analytical methods. The most popular being X-ray fluorescence spectroscopy (XRF), which can quantify the amount of titanium and other elements present. Another method is X-ray powder diffraction (XRPD), which measures the purity of crystalline materials. Other techniques include Raman spectroscopy and inductively coupled plasma mass spectrometry (ICP-MS). To get the most accurate results, a sample of the titanium dioxide should be prepared and examined under controlled laboratory conditions by trained professionals.

Titanium is generally considered harmless for the human body. being both safe and highly biocompatible. As a result. it sees extensive use in medical devices like joint replacements and dental implants. Common consumer products. such as cosmetics and sunscreens. also make use of titanium. However. caution should be exercised with certain types of titanium. like titanium dioxide nanoparticles. which may present a health hazard if inhaled. Additional research is necessary to fully understand this potential risk. In light of this. while titanium is typically safe to use. it is crucial to be aware of its various forms and applications.

Plumber's putty is traditionally used as a sealing material in various plumbing applications, primarily for creating watertight seals around faucets and drains. However, when it comes to PVC (Polyvinyl Chloride) pipes, plumber's putty is not recommended. The oils in plumber's putty can cause the PVC material to break down over time, potentially leading to leaks or pipe damage. For sealing or joining PVC pipes, it's advisable to use products specifically designed for PVC, such as PVC solvent cement. This type of adhesive chemically welds the PVC pipe joints together, creating a strong, watertight seal that is much more suitable and durable for PVC piping systems.
