PARADIM Tools

Four Mirror Xenon High Temperature Floating Zone Furnace

The four mirror Xenon floating-zone furnace is a high temperature optical furnace that can be operated at an elevated temperature between 1500-3000+° C. Accessible via the PARADIM-IQM equipment sharing agreement, users can operate this furnace under a pressure of up to 10 bar of argon, air, oxygen, nitrogen, and other gases. Typical sample size that can be accommodated in this furnace are 4-16 mm in diameter and 1-15 cm in height.

High Pressure Supercritical Fluid Optical Floating Zone Furnace

The first optical floating zone furnace in the world to achieve stable operation at 300 bar of pressure, the high-pressure supercritical fluid optical floating zone furnace enables crystal growth at elevated pressure and temperatures.

Tilted LASER Diode Floating Zone Furnace (LDFZ)

The real-time tilting laser-diode floating-zone (LDFZ) is a new variant of the floating-zone melting technique where the molten-zone is established using a set of near-IR (974 nm) lasers mounted on optical platforms that enables real-time control of angle of incidence. Compared to traditional light sources, laser diodes offer exceptional temperature stability and angled heating imparts additional stability to the molten zone. The result is a highly versatile synthetic capability not only for traditional floating zone growths, but also for travelling solvent growth of incongruent melting materials, as well as the laser pedestal growth of a wide range of specimens.

Ultrahigh Temperature Midscale Induction Bridgman/CZ Furnace

Induction melting is a versatile tool for the preparation of single crystals. Most lab-scale induction furnaces are designed to produce small specimens whereas industrial versions are designed for multi-inch diameter boules. The PARADIM Ultrahigh Temperature Induction furnace is designed to fill the size gap between these two limits, enabling preparation of ca. 1” diameter, multi-inch long, specimens.
