Understanding the Different Types of Ceramic Materials

28 April 2021

The name “ceramics” covers an expansive scope of materials. There are numerous pieces for different applications. With cost-control as a driver, the normal shop needs just to gain proficiency with a portion of the nuts and bolts to begin machining the “machinable” class of ceramic material — like Macor®, alumina silicate, boron nitride and other glass mica composites make up most of this class. The following are the different types of ceramic materials.

Macor® — MACOR® machinable glass-ceramic is a white, unscented, porcelain-like (in appearance) material made out of around 55% fluorophlogopite mica and 45% borosilicate glass. It has no known poisonous impacts; be that as it may, the residue made in machining can be an aggravation. This disturbance can be kept away from by great housekeeping and suitable machining methods.

Alumina — Alumina is the most notable and most normally utilized fine ceramic material. It has a similar sintered precious stone body as sapphire and ruby. It has been utilized for quite a long time in electrical segments for its high electrical protection and is generally utilized in mechanical parts for its high strength, and consumption and wear obstruction.

Aluminium Nitride — Aluminum nitride (AlN) is a specialized ceramic material that includes an amazingly intriguing blend of high thermal conductivity and superb electrical protection properties.

Alumina Silicate (Lava) — By changing interaction conditions, this exceptionally flexible material can be custom-made to give a scope of hardness esteems to suit client prerequisites while keeping up its thermal and electrical properties. This material is superb for the assembling of apparatuses, terminating and dicing plates, and is adequately adaptable to be made into complicated plans indicated by our clients.

Boron Nitride — Boron Nitride (BN), often alluded to as ‘white graphite’ because of its comparable planar hexagonal design and lubricious qualities, is a hard ceramic material with high thermal conductivity and great thermal stun opposition. Dissimilar to graphite it is an electrical cover and albeit not as simple to a machine as the machinable ceramics it is better than other conventional ceramics in this regard.

Graphite — For instance, graphite (a structure, or allotrope, of carbon) is viewed as a ceramic since it’s nonmetallic and inorganic, yet (in contrast to most ceramics) it’s soft, wears effectively, and is a decent conduit of power. So on the off chance that you took a gander at the properties of graphite, you wouldn’t think of it as a ceramic by any means.

Mullite — Mullite is a significant ceramic material for both customary and progressed primary application because of its high-temperature solidness and reasonable properties like high liquefying point, low thermal development and conductivity, high electrical resistivity, great jerk opposition and erosion soundness.

Mycalex® —Mykroy/Mycalex (MM) is a thick ceramic material, contained a mix of mica and glass. In the same way as other ceramic materials, it is a phenomenal cover, and it is regularly utilized as a better option than superior plastics; it is more diligently than most plastics, yet softer than most ceramic materials.

Quartz — Quartz is the mineral type of silica powder utilized in ceramic coatings and mud bodies. The mineral silica “needs to be” when cooled from liquid to strong (it very well may be other things relying upon the speed of cooling). Dissimilar to silica glass, the quartz period of silica is dependent upon reversal and going with volume and structure change when terminated through 573C. Room temperature quartz is called alpha quartz, beta quartz exists just above 573C.
