Material specification
IOTA-8 quartz sand grade
Also known as IOTA-8
The most demanding of the IOTA producer grades held here: more than 99.999 per cent SiO2 with total metallic impurities below 10 mg/kg. Reading it against IOTA Standard is what makes the point that a headline purity is not an impurity profile — its aluminium is 8.0 mg/kg against 14, its iron below 0.05 against 0.3, and its TITANIUM HIGHER, at 1.3 mg/kg against 1.2.
