A shipment of molybdenum disulfide is on its way to customers across the ocean.
On January 30, 2023, molybdenum rose more than 20% in a single day, breaking through a new 17-year high. A shipment of molybdenum disulfide sent by the company's sales team ahead of the Chinese New Year is being shipped across the ocean to customers.
Recently, there are customers to our sales team consulting, and provided the market channel to buy molybdenum disulfide samples (hereinafter referred to as non-molybdenum disulfide), because the non-molybdenum disulfide samples used in the process of lubrication performance and the previous commercial molybdenum disulfide there is a significant difference, far from reaching the required lubrication effect, customers suspect they bought is not the real molybdenum disulfide, hope to help identify.
The following is a simple laboratory procedure for distinguishing molybdenum disulfide from non-molybdenum disulfide methods:
First, the process of discrimination 2-3 grams of molybdenum disulfide and non-molybdenum disulfide were taken respectively, placed in different crucible, crucible forceps into Muffle furnace, roasted at 500-600℃ for 30-40 minutes, compared with the changes before and after roasting, molybdenum disulfide after roasting appearance color changes significantly, non-molybdenum disulfide before and after roasting appearance has no significant change.
