Ceramic Vacuum Break

Vacuum break and electrical isolator.

Ceramic vacuum break.

Alumina ceramic is widely used as an insulator in vacuum devices such as switching and microwave tubes. The typical plating for. Since it has high stability against thermal treatment and a low outgassing rate as well as high dielectric and mechanical strengths it is a suitable material for insulators with good vacuum performance. From 3 4 to 1 1 2 id.

Glazed alumina metallized ceramic pipe for vacuum breaker. Ceramic break is an electrical insulator. Stra val designs and manufactures its own line of vacuum breaker valves. They are also suitable for use with currents of over 1 000 a and voltages exceeding 100 kv.

Cf flanged vacuum ceramic breaks. However up to 8 diameter can be accommodated. It can be formed via dry pressing injection or hot pressing. Vacuum isolators are used to provide an electrical break between the vacuum system and other external components.

The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties mechanical design and the intended operating environment. Metallized ceramic pipe is often made of 95 alumina or higher grade. If you are looking for high quality performing inline spring check valves you have come to the right place. Between 3kv to 40kv.

Provide electrical insulation for water or ln2 cooling lines depending on break type rated for high and ultra high vacuum applications. Liquid break is used to transmit coolant fluid to provide an electrical break in the transmission line. The vacuum sealed ceramic to metal and glass to ceramic components are designed for cryogenic applications and can withstand temperatures of up to 450 c with a leak rate of under 1x10 9 atm cc s helium. Developed in cooperation with tokyo electron the break filter uses the extremely fine pores of porous ceramic material to produce a gas flow control diffuser in breaking a vacuum by utilizing the pressure buffer effect.

Constructed with vacuum grade materials including 304 stainless steel weldable lips high purity alumina ceramic insulation and vacuum tube grade braze alloys. Diameter can be up to 800 mm. Traditionally to break a vacuum in a load lock chamber nitrogen gas was slowly introduced into the chamber in a slow vent. Our vacuum breaker valves are manufactured out of stainless steel 316 or 303 or exotic alloys titanium alloy 20 monel or hastelloy.
