Sapphire glass tube transparent single-crystal alumina
electro-insulation properties
Product description
Sapphire capillary tubes, crafted from single crystal sapphire, are
renowned for their extraordinary resilience and durability, making
them the optimal choice for demanding environments involving
extreme physical conditions.
Due to the inherent strength and exceptional properties of
sapphire, such as its ability to endure high temperatures,
significant pressure levels, and aggressive chemical exposures,
these capillary tubes are incredibly reliable in critical
applications.Particularly noteworthy is the sapphire capillary tube
with an inner diameter of 0.6mm and a wall thickness of 0.2mm,
designed to withstand internal pressures exceeding 100 MPa. This
capability highlights the tube's robustness in handling
high-pressure scenarios without compromise.Leveraging over two
decades of expertise, our manufacturing process has been finely
tuned to produce sapphire capillary tubes of superior quality.
We are adept at crafting tubes with minute inner diameters as small
as 0.1mm, wall thicknesses down to 0.1mm, and lengths that can
reach up to 1500mm. This precision in manufacturing allows us to
meet the specialized needs of our clients across various
industries, ensuring performance and quality that set industry
benchmarks. Whether for analytical applications in laboratories, in
aerospace engineering, or in high-tech manufacturing processes, our
sapphire capillary tubes offer unparalleled performance and
reliability.

Product application
Single Crystal Sapphire is an invaluable substrate material
extensively utilized in various high-tech applications due to its
superior properties. It serves as an ideal base substrate for the
deposition of GaN, pivotal in the manufacturing of blue, green,
ultraviolet, and white High Brightness LEDs (HB-LEDs). Its
excellent thermal and chemical stability, coupled with its ability
to align well with a variety of semiconductor materials, makes it
highly effective for thin film deposition, used in HB-LED
semiconductors, piezoelectric semiconductors, superconductors, and
thin film substrates. Additionally, Single Crystal Sapphire's
robustness and mass productivity meet the demands for future
larger-size substrates, enhancing its utility in precision devices
like MR sensors, precision resistors, and optical devices, as well
as in thin film HICO applications. This broad range of
applicability underpins its critical role in advancing modern
technology sectors.
