信光社 List of Products and Services

This comprehensive catalog introduces: - An overview of Shinko's business - Crystal growth methods - Representative crystals such as sapphire, SrTiO3, and rutile (TiO2). *For more details, please contact us or refer to the catalog.

• Automatic Fire Alarm System

We consistently produce large sapphire crystals in-house (within Japan) using our original TSMG method. It is ideal for the production and application of thick and large sapphire products! Features of our TSMG sapphire: - Constantly cultivating sapphire of the largest class in Japan (φ300×350mm) - Can be processed into any desired shape using NC - Options for high-transmittance optical grade in the ultraviolet range (235nm and above) and relatively inexpensive semiconductor grade - Orders can be placed starting from just one piece *For more details, please contact us or refer to our catalog.

• Other measuring instruments

We are a long-established sapphire manufacturing company with 77 years of history. Since we cultivate large sapphire crystals in-house, we can produce fine products under 1mm as well as large windows around 300mm, as shown in the photo. We excel at closely aligning with our customers' requirements from the design stage, collaboratively creating custom products that are optimal in terms of quality and cost. Inquiries for single units are also welcome, so please feel free to contact us. In addition to basic processing such as cutting, grinding, and polishing, we also support special processing such as drilling, ultrasonic processing, laser processing, tube processing, and coating. Furthermore, please utilize our sapphire products, which have excellent chemical resistance, in semiconductor manufacturing processes that use strong acids and strong alkalis, which can cause quartz glass to become opaque. *We are currently offering the results of chemical resistance tests for sapphire products. Technical documentation can be downloaded from the link below. 【Features】 ■ Chemically stable (almost insoluble in acids and alkalis, does not become opaque) ■ Wide transmission characteristics (UV to near-infrared (approximately 5μm)) ■ Hard (Vickers hardness: 1750 (A face)) ■ Heat resistant (melting point: 2040℃) ■ Good thermal conductivity (42W/mK at 25℃)

• Vending machines

Sapphire has the following characteristics: - Wide transmission properties (UV to near-infrared (approximately 5μm)) - Hardness (Vickers hardness: 1750 (a-plane)) - Chemically stable (almost insoluble in acids and alkalis, does not lose transparency) - Heat resistant (melting point: 2040°C) - Good thermal conductivity (42W/mK at 25°C) Due to its strength to withstand harsh environments and excellent optical properties, it is one of the materials that can solve the challenges of glass and fluorides. In recent years, it has become possible to grow large crystals of about 300mm, allowing for a wider range of applications.

• Manufacturing Equipment

- TiO2 has three types of crystal structures, and Shinkosha provides crystals with the rare rutile structure found globally. - Due to its high refractive index, birefringence, and wide transmission characteristics, it is used as an optical core component. - In the field of photocatalysts, it is also used for fundamental research that takes advantage of the characteristics of single crystals. - Because of its good crystallinity and the ability to perform step & terrace treatment on the surface, it is widely used as a substrate for thin film deposition.

• Solar power generation

The SrTiO3 (STO) substrates from Shinko Electric Industries have been a long-selling product favored by thin film researchers around the world since the 1980s. We also offer options such as Nb-doped products with conductivity, step and terrace treatment, and break groove (chocolate bar-shaped) processed products.
