TRANSPARENT FUSED SILICA / QUARTZ

Transparent fused silica / Quartz rock crystals are mined in a similar fashion to that of coal, and processed via crushing and acid washing, forming various sizes.                                                                                                                                                                                                                                          Rods and tubes can then be drawn in many different sizes and configurations.

Fused silica or fused quartz is glass consisting of silica in amorphous (non-crystalline) form,

The main difference being that it contains no other ingredients usually added to glass to lower the melting point for workability, therefore leaving the virgin fused silica / quartz material with a much higher melting & ultimately working temperature.

All this of course is quite different from the Translucent / Opaque fused silica, which is of course made from sand.

Some of the typical industries and uses are Semiconductor, ultraviolet, solar, optical lenses, Lighting along with many other related industries that enjoy some of the unique property advantages such as Mercury  Vapor Lamps for street lighting, Automobile Lamps, Stadium Flood lights Etc and many others for either the extreme resistance to thermal shock and the high transparency from the ultraviolet through the infra-red spectral range as-well as precious metal thermocouple’s

The enormous versatility of Fused Silica (Quartz) is also shown in the images below depicting precision engineered parts

Our workshops are extremely well equipped with state of the art CNC machines including a 5 axis machining center and a specially adapted / specked Studer cylindrical grinder that can go up to 650 mm diameter with internal grinding and slotting capabilities giving much better dimensional control by removing secondary operation stages.

These machines are of course all used for the manufacture of  precision technical ceramic parts also, and are all backed up with a Mitutoyo CMM that can measure to four decimal places.
