Product Detail

▼ Introduction of Macor Grade Machinable Glass Ceramic

Macor Grade Machinable Glass Ceramic from UNIPRETEC is a white, odorless, porcelain-like (in appearance) material composed of approximately 55% fluorophlogopite mica and 45% borosilicate glass. Machinable glass ceramic is a new class of ceramic material which is capable of being machined to precise tolerances using conventional metal-working tools and equipment. There are a number of useful machining techniques which are pertinent to this material.


▼ Features of Macor Grade Machinable Glass Ceramic

 √ high use temperature (800°C continuous; 1,000°C peak);
 √ low thermal conductivity and it is a useful high temp. insulator;
 √ it can be thick or thin film metallized, brazed, epoxy and frit bonded;
 √ it is strong and rigid. It unlike high temperature plastics will not creep or deform;
 √ it is radiation resistant and plays a key role in nuclear applications and nuclear-related R&D;
 √ it is white and can be highly polished. It is the perfect material for medical and optical devices;
 √ excellent electrical insulator and it is used throughout the semiconductor and electronic industries;
 √ no porosity and when properly baked, it will not outgas. It is widely used in ultra high vacuum applications;
