Basic Information

Model name : Tabletop Single Crystal Growth Furnace

Since its launch in 1972, Canon Machinery floating zone single crystal growing equipment has expanded globally with model variations and performance that meets diverse needs, from research to industrial use. It was also used to conduct experiments in low Earth orbit on the NASA Space Shuttle (FUWATTO ’92 First Material Processing Test). Leveraging small image furnace development and other expertise accumulated up to now, Canon Machinery partnered with the National Institute of Advanced Industrial Science and Technology to conduct joint development based on the “iConcept*” to commercialize a compact and affordable floating zone single crystal growth furnace.
From youth science instruction to student physics experiments and education, this product is expected to meet a wide range of needs including fundamental research on physical properties and the development of new materials.
*iConcept: Technologies realizing the three i’s.

1. Technologies realizing ai (love) for the environment and human beings.
2. Technologies realizing intelligence
3. Technologies realizing individuality.


Oxide superconductivity, magnetic materials, dielectric materials, etc.


1.Heating area : High temperatures up to 2,100°C are easily obtained.

2.Heating source : Due to infrared heating, it is possible to grow single crystals, such as oxides, which do not melt under high-frequency dielectric heating.

3.High purity : As this is a floating zone system, a crucible is not required and impurities are avoided, resulting in highly pure single crystals.

4.Atmosphere : Isolation in a quartz tube enables the growth of single crystals in optimal atmospheric gas.

5.Crystal growth : The traveling solvent method enables the growth of single crystals with decomposed melt offering oxide superconductivity and other properties.
