Description
Silicon is a classic semi-metal and therefore has the properties of both metals and non-metals. Pure, elemental silicon is grey-black in colour and has a typical metallic lustre, often bronze to bluish.
Silicon is an elementary semiconductor. Like very few other substances (such as water), silicon has a density anomaly: its density is higher in liquid form than in solid form.

* This is a recommendation based on our experience with these materials in our sputter guns. Rates are based on unbonded targets and are material specific. Bonded targets should be operated at lower power to avoid bonding failure. Bonded targets should be operated at 20 watts/square inch or less depending on the material.
