Ceramic Vacuum Break

Cryogenic and vacuum breaks are not suitable for water service because of corrosion while water and vacuum breaks are not suitable for.

Ceramic vacuum break.

Ceramic break is an electrical insulator. 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. 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. Traditionally to break a vacuum in a load lock chamber nitrogen gas was slowly introduced into the chamber in a slow vent.

Provide electrical insulation for water or ln2 cooling lines depending on break type rated for high and ultra high vacuum applications. Vacuum isolators are used to provide an electrical break between the vacuum system and other external components. From 3 4 to 1 1 2 id. Constructed with vacuum grade materials including 304 stainless steel weldable lips high purity alumina ceramic insulation and vacuum tube grade braze alloys.

Metal ends to provide a means of attaching to a vacuum chamber. Cryogenic and in vacuum breaks consist of ceramic insulating tubes with metal tubes brazed to each end and welded to iso for high vacuum hv or cf flanges for uhv service. We are able to manufacture a diversity of different specification metallized ceramic pipe the max. 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.

It can be formed via dry pressing injection or hot pressing. If you are looking for high quality performing inline spring check valves you have come to the right place. Vacuum break and electrical isolator. They are also suitable for use with currents of over 1 000 a and voltages exceeding 100 kv.

Alumina ceramic is widely used as an insulator in vacuum devices such as switching and microwave tubes. The typical plating for. Metallized ceramic pipe is often made of 95 alumina or higher grade. Stra val designs and manufactures its own line of vacuum breaker valves.

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. Diameter can be up to 800 mm. Visit the online store for vacuum sealed ceramic metal and glass ceramic composites at ceramtec north america. However up to 8 diameter can be accommodated.

Our vacuum breaker valves are manufactured out of stainless steel 316 or 303 or exotic alloys titanium alloy 20 monel or hastelloy. Glazed alumina metallized ceramic pipe for vacuum breaker.
