Costing
Certainly, costing is an essential element. However, it should not overshadow the quality. As mentioned earlier, this metal is obtained with great difficulty. When accompanied with high prices quality comes, it is imperative to consider the overall value. Consider all the prices. Such expenses include shipping, handling, and possible future investments arising from quality products in the short or long run. Only settle for the costs that guarantee the best value in the long run.
A1.Molybdenum enjoys expansive uses in areas that require durability, thermal stability, electrical conductivity, and chemical retardance. Also, it is used for making X-ray tubes. Moreover, it is applicable in the aerospace industry. This suits components of arcjet nozzles, filaments, electrical contacts, and even in machining tools, mixing tanks, furnaces, and alloys. The metal has a notable resistance to corrosion as well as oxidation. Hence, it is a staple in industries that deal with ever-corrosive acids like sulfuric and hydrochloric.
A2.Usually, molybdenum presents no adverse effects when exposed to average concentrations in the atmosphere. However, when it exceeds recommended levels, it poses adverse health effects. Such levels cause irritation of the eyes, lungs, skin, and even the digestive system. Also, it has been classified under possible carcinogens. At times, exposure to occupational levels may cause adverse effects like reproductive toxicity, respiratory complications, or fibrosis. These effects may pose risks to health upon cumulative or long-term exposure without suitable respirators.
A3. Usually, molybdenum rods present minimal risks to health when ‘met’ with average environmental concentrations. However, higher concentrations cause irritation of the eyes, skin, and respiratory tract. Molybdenum dust or fumes are hazardous when inhaled. It can therefore accumulate in the lungs, leading to pulmonary fibrosis. Also, ingesting high amounts of molybdenum may cause stomach distress. Frequently, it interferes with copper absorption, potentially resulting in copper deficiency. In industrial settings, moderation of inhalation and skin contact is crucial.
A4. Studies have shown that molybdenum presents negligible danger when encountered in moderate quantities. However, exposure to elevated concentrations causes eye irritation, nausea, and potential copper absorption interference. In workplaces, evaluating the inhaled amount is critical. This is because respiratory protection is crucial when handling molybdenum dust.
