Sapphire is a high purity and high density, single crystalline form of aluminum oxide, which may contain chromia, titania, yttria, or other dopants. Sapphire is usually transparent or translucent. Sapphire ceramics are used in lasers, substrates, jewel bearings, watch crystals, or other specialized optical, wear and electronic applications. Ruby, corundum, and topaz are other names for natural or synthetic sapphire. Ruby is chromium doped sapphire used in optical filters and laser rods. Products & Services
Ceramic manufacturing services for parts and assemblies made of ceramic or refractory materials.
Ceramic balls are rolling, spherical elements that are used in check and ball valves, bearings, and other mechanical devices that provide rotary or linear motion. They can provide higher stiffness, lower thermal expansion, lighter weight, increased corrosion resistance, and higher electrical resistance than comparable steel products.
Sapphire materials and components consist of a single-crystal, ceramic form of aluminum oxide. They have superior hardness, mechanical and optical properties, and are used in jewel bearings, lasing rods, wear parts, wafer substrates and optics.
Balls and sphere shapes are used for check or ball valves, bearings, or other applications requiring a spherical product. They are fabricated from materials such as carbides, ceramics, sapphire, metals, plastics, rubber and elastomers.
Ceramic tube and ceramic rod products are suitable for use in applications requiring high temperature strength, erosion resistance, electrical or thermal insulation, and other specialized characteristics.
