What is the weakness of graphene

The main disadvantage of graphene as a catalyst is its susceptibility to oxidative environments. To grow graphene, toxic chemicals are used at high temperatures. Due to this, it exhibits some toxic qualities. Diamond is rarer than graphite because the bonds formed in the diamond are stronger and need high energy and pressure, whereas graphite can be formed in normal conditions. Tesla has agreed to a deal with Magnis Energy Technologies, which makes materials for electric-vehicle batteries, to secure graphite supplies. Graphite mining in Sri Lanka has occurred since the Dutch occupation of the country. In commercial quantities, it is the only country in the world to produce the purest form of graphite, vein graphite (also known as lump graphite), which currently accounts for less than 1% of the world's graphite production. Inhalation Toxicity: Graphite alone may cause respiratory tract irritation but is not listed as a carcinogen. However, it may contain impurities of crystalline silica which are listed as a carcinogen.

Inhalation of dust over prolonged periods may cause pneumoconiosis. Graphite dust may irritate the eyes and cause stinging, watering, and redness. Contact with this dust may be abrasive and mildly annoying to the skin, but absorption is unlikely2. Graphite is not poisonous if you swallow it, but it can be a choking hazard. Puncturing your skin with a pencil is not poisonous but can lead to infection. The substance can be absorbed into the body by inhalation. A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. Repeated or prolonged inhalation of dust may cause effects on the lungs. This may result in graphite pneumoconiosis. If you are looking for high quality, high purity, and cost-effective graphite, or if you require the latest price, please email contact mis-asia.
