Containers made of single crystal sapphire are resistant to corrosion from hydrochloric
acid, sulfuric acid, nitric acid, etc.
Our company can produce container/crucible shaped sapphire by growing tubes from a seed crystal base with
our unique EFG growing methodology.
As sapphire is a transparent material, it can be confirmed visually if a container has acids inside, such as
those mentioned above, helping to avoid dangerous misuse.
Sapphire has many superior properties including heat resistance, scratch resistance, corrosion resistance
and plasma resistance. It is optimal for observation of molten and/or high temperature material as it
maintains transparency even under high temperatures that quartz glass cannot withstand.
In this way sapphire containers ensure the same transparency and wettability as glass even in environments
in which glass cannot endure.
Although Teflon may be selected as a common material for various analyses, repeated use can cause
contamination to stick to the surface and discoloration to occur.
Since sapphire eliminates surface contamination and controls dust generation, its applications extend to
components analysis that require visibility and corrosion resistance, such as observation in liquid.

Customized Sapphire Processing Examples
Because sapphire has a hardness (HV2300) which ranks second to diamond, it cannot be cut like common metal. Moreover, sapphire is an insulator material, so electrical discharge machining is not possible either. Therefore, fine hole drilling (um order of magnitude) is carried out using customized Fs (Femtosecond) laser and UV laser processing. In addition, it is also possible to apply polishing process to holes with diameters over 35um.
