Silicon is a metalloid and carries the typical properties of both metals and nonmetals. It is extremely inert and insoluble in water and acids. However, it can be dissolved into silicates by hot alkaline lyes. Pure silicon forms dark gray, metallic, shiny crystals. Silicon also has excellent thermal conductivity, which – in pure silicon – is accompanied by extremely low electrical conductivity. When alloyed with aluminium, it enhances strength and reduces weight.
High purity evaporation materials play a huge role in deposition processes to ensure high quality deposited film. Stanford Advanced Materials (SAM) specializes in producing up to 99.999% purity silicon evaporation materials using quality assurance processes to guarantee product reliability.
