ionic solid- high boiling points
Ti - 4+
10^-7m
reflects harmful UV, or transparent so doesn't leave white marks
could catalyse harmful reactions due to high surface area to volume ratio?

kerosene - aircraft fuelSubmit reply

diesol oil - cars and trains
lower viscosity, higher ease of igntion etc
