Exceptionally wearresistant Dimensionally stable even at high temperatures Electrically insulating Frequency neutral

Various methods of assembly exist to bind ceramic to metal. When it comes to make an assembly that can resist to mechanical stresses and/or high temperatures, be vacuum leak tight and withstand corrosive environment, high temperature, braze sealing is essential. Applications Ceramic-to-metal brazed assemblies are particularly suited for use in airborne electronics for the aerospace, defense devices, medical and analytical instruments,high-energy physics, high vacuum equipment, the nuclear industry... We offer customized ceramic to metal brazed assemblies such as for instance : high-voltage feedthroughs for the mass spectrometry, hermetic packages for airborne electronics or sensors for the oil industry, high-voltage hermetic connectors for the nuclear industry, high-voltage insulators for electron tubes.

Dryclay preparation is a key POITTEMILL process. Finegrinding stands as a landmark innovation in raw material mix preparation. The satisfaction of those adopting finegrind processing justifies POITTEMILL's development Our solution has many process advantages we can treat clay impurities totally (lime, pyrite or calcium carbonate for instance), allowing the use of raw materials previously unfit for the production of highquality finished products. The outer appearance is smoother, with a perfect skin, giving to finishes products a greater commercial value. By grinding the raw materials to an ultrafine powder, a greater homogeneity is achieved that reinforces the internal shard and mechanical strength of tiles / inner wall blocks.

The dimensions of the dowel pin comply with DIN 6325. Advantages: Ideal for fixture construction Dimensionally stable even at high temperatures Electrically insulating

Parallel keys are used for the implementation of shaft-hub connections. These are positive connections which are used to transmit torque.

Form A locating pins are used to position workpieces and fixture parts in reamed holes. The flattened Form C can be used to bridge tolerances in hole spacing or to secure the part to be positioned in one direction only. The Form A locating pins can also be used as limit stops or fixture feet. Advantages: Cerazur is extremely impact and bend resistant. The basis of this material is zirconium oxide. It is a composite metal-ceramic material. Drawing reference: Form A and B: cylindrical locating pin Form C and D: flattened locating pin

Version: Ground. Top face without centerbore. Note: Rest pads can also be used as feet for jigs and fixtures. Advantages: Cerazur is extremely impact and bend resistant. The basis of this material is zirconium oxide. It is a composite metal-ceramic material.

Ceramic bearings Si3N4. Bearing cage PTFE. For most applications Si3N4 is the preferred material for ceramic bearings. Silicon nitride bearings are light, very hard and highly wear resistant. High and ultrahigh performance bearings are used in e.g. aerospace technology, metal production industries (high application temperatures), machine manufacturing, chemical industries (chemically aggresive substances), pharmaceutical and medical industries, semiconductor and biotechnology (clean room enviroments which may not be contaminated by lubricants). On request Special version with PEEK ball cage. Without ball cage.

The special taped seams increased strength and provide an effective barrier to particles. Disposable protective coverall WeeCover Max 1 Blue provides a high level of lightweight and comfort. Breathable fabrics and ergonomic style pattern help to reduce the risk of heat stress. BONUS ADDON Overboots system attached to the suit with elastics. The overboots pattern ensure a fully protection in critical areas.

Ceramic components offer significant advantages over metal and plastic parts . They have a dimensional stability at high temperatures. They are good electrical insulators. They do not outgas in vacuum environment. Ceramics are inert materials and resistant to many gases and chemicals. They show high thermal insulating properties or high thermal dissipation. Applications and products Advanced ceramics are used in solid-state lasers (Nd-Yag..), gas lasers, fibre lasers, diode lasers, high-power laser diodes, IPL, as well as in optoelectronic devices - optical optical sensors / imaging, infra-red detectors... Typical customized products from Microcertec are electrical insulators resistant to gas corrosion and plasma discharges, reflectors, heat sinks, 3D metallized sensor carriers, structural parts than can be brazed, sensor holders.

Microcertec manufacture ceramic reflectors for lasers and IPL systems. We offer customized reflectors that are primarily manufactured from high-reflectivity alumina and subsequently glazed over in order to guarantee leak-tightness and protection. The base material - reflective alumina - was developed specificaly for this application. It offers a high reflectivity from visible to near infra-red. Reflectors are machined / ground against customer's drawing. Quantities range from prototype to production quantities. Glazing protects the surface in preventing adhesion of impurities and primarily ensures leak tightness of the reflectors. Compared to metal reflectors, ceramic units offer higher reflectivity and therefore enhanced laser power. They also have the advantage of being more resistant to temperature variations and erosion from cooling fluids, hence leading to extended operating life. Applications The following applications require ceramic reflectors in order to ensure a high...
