Composition of Macor

Precision Ceramics is a Macor Distributor. Precision Ceramics is a Macor Expert. In fact, there is no other Macor Supplier who knows more about this unique machinable glass ceramic than Precision Ceramics. We're also experts in Macor Metallization and publishers of the Macor Technical Bulletin.

Macor machinable glass ceramic is a white, odourless, porcelain-like (in appearance) material composed of approximately 55% fluorophlogopite mica and 45% borosilicate glass.

It has no known toxic effects; however, the dust created in machining can be an irritant. This irritation can be avoided by good housekeeping and appropriate cleaning techniques.

The material contains the following compounds:

Compound	ID	Weight (approx.)
Silicon	-SiO²	46%
Magnesium	MgO	17%
Aluminium	Al²O	16%
Potassium	K²O	10%
Boron	B²O	7%
Fluorine	-F	4%

Microstructure

The photgraph below shows the microstructure of Macor glass machinable ceramic with 5000x magnification. Randomly oriented mica flakes in the microstructure of Macor glass machinable ceramic are the keyo its machinability.

Macor® is an outstanding engineering material and is machinable with ordinary metalworking tools. Macor is also a problem solving material combining the performance of a technical ceramic with the versatility of a high performance plastic.
