Transparent aluminium is also referred to as aluminium oxynitride. It is a see-through ceramic of polycrystalline that is made from a structure of oxygen, nitrogen, and aluminium. This impressive material looks completely see-through and is incredibly strong. Transparent aluminium is four times as hard as fused silica glass, three times harder than steel, and a whopping 85% harder than sapphire.
Not only is transparent aluminium very tough, but it also has an extremely high melting point and can remain solid up to 1200 degrees Celsius. This means it can be used for products which need to withstand super high heats while also being see-through. Transparent aluminium is also resistant to damage caused by oxidation and radiation and offers good resistance to corrosion.
I bet it's prone to flaking or something like that, they're going to put it everywhere and only then will we find out "oh btw it causes Alzheimer's lolol"
