LOT OF TWO 2" LONG HEXOLOY SINTERED ALPHA SILICON CARBIDE CERAMIC TUBE REFRACTORY WIRELESS HEATER ELEMENT No.: 62 The specifications for these components are as follows: Length: Average approximately 2” +0.010"/- 0.005" (76.2 +/- 0.010 mm) Outside Diameter: Average approximately 0.550” (14 mm) Inside Diameter: Average approximately 0.410” (10.5 mm) You are buying a LOT OF TWO  2" Long High Purity Hexoloy® SA Sintered Alpha Silicon Carbide Ceramic Tube. They are in New Old Stock condition. They are made from high purity Silicon Carbide (SiC). Hexoloy® SA is a premium wear resistant ceramic material. Hexoloy® SA is produced by pressure-less sintering submicron silicon carbide powder. The sintering process results in a self-bonded, fine-grain (less than 10 µm) SiC product which is extremely hard, lightweight, and dense. It has very low porosity and chemical inertness enabling it to function in environments of hot gases and liquids, oxidizing and corrosive atmospheres, as well as strong acids and alkalis even at extremely high temperatures. Hexoloy® SA can be produced in various complex shapes, tubes, or tiles, which can be ground and finished to close tolerances. Hexoloy® SA SiC's excellent erosion and wear resistant properties make it ideally suited for the most demanding wear problems encountered in heavy material handling industries. The single-phase composition of Hexoloy® SA SiC enables it to reliably perform in air at temperatures in excess of 1300° C (2372° F). Oxidization resistance is also important for certain high-temperature applications. Hexoloy® SA SiC, due to its high purity and high density, is more stable in long-term applications because it is more oxidization resistant. It may be used in vacuum or inert gas environments to 2200° C (3992° F). Because of its high thermal conductivity and low coefficient of thermal expansion, it is very resistant to thermal shock and will survive rapid thermal cycling as compared to other refractory materials. Hexoloy® SA SiC exhibits excellent strength at room temperature and maintains that strength even at elevated temperatures due to its single-phase fine-grain structure. Hexoloy® SA SiC's compressive strength is 10 times greater than its tensile strength. This is an important consideration when designing with ceramics due to an inability to yield and relieve stresses like metals when placed in tension. Care should be taken to chamfer or radius all edges. This material has very high hardness, very high stiffness, very good corrosion resistance to chemicals at high temperature, and very high refractoriness or use temperature. They may be used for a variety of electrical, mechanical, and thermal applications. They may be used as setter plates for firing parts in a kiln. The may be used for high temperature furnaces. They may also be used as “Wireless Heating Elements” in the microwave. Using fibrous thermal insulation the SiC will absorb the microwave and convert it to infrared radiation, i.e. red heat. They may also be used for jewelry or for applications requiring high wear or abrasion resistance. Your imagination is the only limiting factor in the spectrum of possible applications for this component. Be sure to view all photos as they are an integral component of the item description. Please Note: These are precision technical ceramic components. There is no warp or camber Specification for this item. However they are relatively round overall. There may also be “firing” color variations inherent in the material. The photos do not always do justice to color. There are very dark grey to black. The background is Jet Black Felt. The specifications for these components are as follows: Length: Average approximately 2” +0.010"/- 0.005" (76.2 +/- 0.010 mm) Outside Diameter: Average approximately 0.550” (14 mm) Inside Diameter: Average approximately 0.410” (10.5 mm) Please Note: These are not precision technical ceramic components. There is no warp or camber Specification for this item. However they are relatively straight and round. These have only been rough cut.
