Having said that, this is where they start diverging. Silicon is far lighter which has a density of 2.33g/cm3, making it ideal for excess weight-sensitive applications and under fifty percent the density of germanium. Additionally, it is much more thermally resistant than germanium and that has a Knoop Hardness of 1150 It is additionally more durable and fewer brittle. Silicon also prices significantly less read more which makes it an improved applicant in numerous applications.
Just one quite common scenario we see germanium utilized is inside higher and lower pace wind tunnels for jet propulsion experiments. Typically, these Home windows are much bigger than stock configurations reaching sizes in excess of 190-200mm.
