LOT OF SIX (6) SMALL STEATITE TUBES 0.180” x 0.120” x 0.935” LONG No.: 220

Description: LOT OF SIX (6) SMALL STEATITE CERAMIC TUBES No.: 220 Outside Diameter: Approximately 0.180” +/- 0.005" (4.82mm)Inside Diameter: Approximately 0.120” +/- 0.005" ( 3.10mm)Wall Thickness: Approximately 0.033" +/- 0.001" (0.84 mm)Length: Approximately 0.935" +/- 0.005" (55.6 mm) You are buying one Lot of Six (6) Small Steatite Ceramic Tubes in mint condition being NOS (New Old Stock). They are made from high purity Steatite. (MgO·SiO2) which of course is a Magnesium Silicate. It is in the Talc/Enstatite family of minerals. They are easily cut to size with a diamond blade Dremel tool. Steatite is a low cost material with high electrical resistance at high temperatures, good mechanical strength and a very low dielectric loss factor. Such properties make it ideal for high frequency, low loss, and high voltage insulation. Moreover, steatite is an excellent material for electrical engineering as it can be readily shape sintered into a wide variety of forms such as washers, bushings, resistor forms, spaces and beads. Steatite has been used for many years in large-scale industrial systems, household electronic appliances, aerospace and automotive applications; and in specialized electro-technical instruments such as cathode-ray tubes. This material has very good corrosion resistance to chemicals and high refractoriness or use temperature. They may be used for a variety of electrical, mechanical, and thermal applications. It may be used for high temperature furnaces as thermocouple and sensor insulator tubing. It may also be used for jewelry as beads when cut small. 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. The specifications for these components are as follows: Outside Diameter: Approximately 0.180” +/- 0.005" (4.82mm)Inside Diameter: Approximately 0.120” +/- 0.005" ( 3.10mm)Wall Thickness: Approximately 0.033" +/- 0.001" (0.84 mm)Length: Approximately 0.935" +/- 0.005" (55.6 mm) Please Note: There are visually discernible differences in any or all of the dimensions. These are not precision technical ceramic components. There is no warp or camber Specification for this item. However they are relatively straight and round. There may also be “firing” color variations inherent in the material. The thermal shock resistance is not very high so exercise rule of thumb caution. “The larger the piece of material the slower the rate of temperature increase should be applied to the piece.” Heat up slowly to avoid cracking in use.
