Would it be true to say that silicon and germanium are used as alloys?
yes we silicon is a alloy.
What are things made of germanium?
because of germanium oxide´s (GeO2) high refractive index, about 10% of worldwide germanium consumption is from optical uses such as lenses to cameras and centres of fibre cablesanother use of germanium is as a catalyst for polymerisation of polyethylene terephthalate, the plastic in most water bottles. germanium is also used in an alloy with silicon for semiconductors that can be faster then those with only silicon.
Is germanium reactive?
germanium reacts naturally
What is the atomic symbol of germanium?
Germanium is Ge.
Is germanium a element?
Yes, germanium is an element.
Is germanium an alloy or not?
not

How is germanium used inside computer chips?
It is not, silicon is. It is not possible to make ICs commercially using germanium (mostly because its oxide is crumbly and water soluble unlike silicon's oxide which is a stable and insoluble insulator, which means germanium ICs must be wired by hand under a microscope which is too costly for production). This means that germanium is limited to usage in discrete components (transistors & diodes) only. Some work is being done using silicon-germanium alloy for ICs, but it is not in the market yet.
How does a germanium diode look like?
Germanium diodes can be point contact, grown junction, alloy junction, diffused junction, or surface barrier; each type is made differently.point contact, a sharp pointed metal wire is pressed against the surface of a piece of germaniumgrown junction, as a boul of germanium is being pulled a quantity of the opposite dopant is added to the molten germanium, the boul is then sliced on opposite sides of the junction and diced into individual diodesalloy junction, a pellet of alloy containing the opposite dopant is placed on a piece of germanium and heated until it alloys into the surface of the germaniumdiffused junction, dopant of the opposite type of a piece of germanium is applied and heated to allow it to diffuse into the germaniumsurface barrier, a piece of germanium is carefully cleaned then metal is electroplated on a small spot on its surfaceNote: these are significantly over simplified descriptions (other than the grown junction method only one device can be made at one time). Note: all of these methods have also been used to make germanium transistors.
Is hallmark 935 platinum or silver?
935 is the purity for Argentium silver. Argentium silver is NOT sterling silver. It is a different alloy which has germanium in it which makes it less prone to tarnishing. Sterling is an alloy that has more copper in it. The copper is added to fine silver in order to make it stronger.

Is germanium toxic?
Germanium compounds are toxic.
What does germanium do?
Germanium does no "do" anything.
Who is Germanium manufactured?
Germanium is not manufactured; its ore is mined then refined into germanium.
Is germanium a insulator of electricity?
Germanium is a semiconductor
Is germanium reactive?
germanium reacts naturally
