VACUUM EVAPORATION SOURCES –

view catalog sheet (PDF)

The AL2O3 coated evaporation basket was first introduced by CM in 1957. Since that time these evaporator baskets have proven to be vital to the vacuum metallizing industry. The parts consist of either tungsten or molybdenum wire formed into baskets and set at 1500O C in hydrogen atmosphere. These are then coated with pure AL2O3 which is sintered in H2 to form the crucible configuration with an internal heater. Because of the intimate internal contact between the heater wire and the crucible structure and the resulting outstanding heat transfer characteristics, vaporization of the material to be deposited may be achieved at lower heater temperatures, resulting in longer evaporator life.

Another advantage which cannot be overlooked is the excellent directional characteristics of these baskets which is controlled by the wall configuration.

The coated evaporator basket is an important step forward in the field of vacuum deposited films as a means of achieving higher quality in both research and production. This catalog features only those units which have become standard through repeated demand. However, our techniques of manufacturing permits to the fabrication of many different sizes and configurations at nominal cost. Upon receipt of a brief sketch, we will submit a quotation on your specific requirements.

TUNGSTEN HEATERS FOR DISPENSER TYPE CATHODES

In response to the increasing demand of heaters to be used in conjunction with dispenser cathodes (Phillips Cathodes) CM has developed a standard set of heaters as indicated in prints No. R-336-7. These, which are available for stock, represent only a fraction of the many types of manufactured by CM. The majority of heaters are fabricated to customer prints.

Heaters cathodes systems of the dispenser type are finding wide use in both research and industry in Laser applications, power tubes and in general electronic research.

CM-Incorporated designs and manufacturers all types of belt conveyor furnaces, batch-type retort equipment, combustion tube, laboratory and crystal growing furnaces, alloy hearth atmosphere furnaces and tungsten rod heating elements units to 2200o C. Although many are of standard design and construction, we welcome your inquiries regarding special applications.
