微晶玻璃陶瓷

 微晶玻璃陶瓷又稱可加工陶瓷,是以合成云母為主晶相的云母微晶玻璃,是一種可以機加工的陶瓷材料,該材料具備了良好的加工性能、真空性能、電絕緣特性及耐高溫、耐化學腐蝕等優良性能。

一. 加工性  

 微晶玻璃陶瓷最突出的特性是可用標準金屬加工工具和設備進行車、銑、刨、磨 、鉆、鋸切和攻絲等加工。是一般95瓷、氮化硅瓷等絕緣材料無法比擬的。微晶玻璃陶瓷 加工性能類似于鑄鐵,它能加工成各種形狀復雜,精度要求高的產品。微晶玻璃陶瓷雖系脆硬材料,但只要合理地確定加工工藝路線及裝夾方式,注意加工方法,準確地選擇切削用量,在一般設備上公差等級可控制在IT7級,光潔度達到0.5μm,加工精度控制在0.005mm是完全可行的。如加工設備優良,操作技術熟練,則精度可達μ級。

二.  電性能

微晶玻璃陶瓷是一種優良的高溫電絕緣材料,在許多電器設備中都可以應用,它有很高的電絕緣強度,高體積電阻及低介質損耗。

.   熱性能

 微晶玻璃陶瓷是一種耐高溫絕緣材料,同時又是能在超低溫領域廣泛使用的耐腐蝕電絕緣材料。它的使用范圍在-270~+800℃。由于微晶玻璃陶瓷中的云母晶體具有一定的彈性,能制止微裂紋的延伸,因此它又具有較好的的抗熱沖擊性能。它的低熱膨脹系數保證了工件的尺寸穩定,可進行氣密封結。

四.  其它性能

微晶玻璃陶瓷經過180℃烘烤,160℃保溫1小時,真空老練8小時,放氣率為

9×10-9 ml/s. cm2 它不導磁,比重是普通鋼材的1/3,比鋁還輕,吸水率極低。

由于它完全由無機材料組成,因此還有不老化不變形,對各種有機溶劑十分穩定及良好的耐酸堿腐蝕性能等。

應用

 微晶玻璃陶瓷由于它具有各種優良綜合性能,能滿足高精度技術要求,無須模具設計及制作大大縮短研制周期,可以加速工程進展,節省研制費用,因此深收廣大科研、教學和設計部門的歡迎。它特別適合汽車、軍工、航空航天、精密儀器、醫療設備、電真空器件、電子束暴光機、紡織機械、傳感器、質譜儀和能譜儀等儀器中廣泛使用。對于一些薄壁的線圈骨架,精密儀器的絕緣支架,形狀復雜等精度要求高的器件,微晶玻璃陶瓷更為適用,它可加工成任意形狀。它比氮化硼強度高,放氣率低,比聚四氟乙烯耐溫度,不變形,不變質,經久耐用,比氧化鋁瓷更好加工性好,生產周期短,合格率高,設計人員可任意制作所需尺寸的產品。

可加工陶瓷抗熱沖擊性能非常好,從800℃急冷至0℃不破碎,200℃急冷到0℃強度不變化。

可加工陶瓷的優良性能使其在航空、航天、電子基片、耐高溫絕緣骨架、離子鍍膜、真空鍍膜、離子顯微鏡、離子加速器、激光器和醫療設備等領域得到了廣泛應用。

With Machinable Glass Ceramic (MGC), fabrication is fast - because it can be machined into complicated shapes and precision parts with ordinary metal working tools, quickly and inexpensively, and it requires no post firing after machining. That means no frustrating delays, no expensive hardware, no post fabrication shrinkage, and no costly diamond tools to meet specifications.

  If you need the performance of a technical ceramic - (high use temperature, electrical resistivity, zero porosity) - and your application demands the ready fabrication of a complicated shape - (quickly, precisely, privately), look at us  .  We will lower your costs and substantially reduce the time between design and actual use.

M.G.C (Machinable Glass Ceramic)

MGC: Machinable Glass Ceramic have the following power feature

 a) Is Machinable with ordinary metal working tools.

 b) Allows Fast Turnaround,no post firing required.

 c) Holds Tight Tolerances, up to .0005"

 d) Withstands High Temperature, up to 800

 e) Is Clean, no outgasing and zero porosity

MGC: Machinable Glass Ceramic have the following applications:

 a) Electrical or Thermal Insulator

 b) Structural Components

 c) Semi-Conductor Processing

 d) Electrical and Opto-Electronic Equipment

 e) Many Other Uses

Used environments:

 MGC Machinable Glass Ceramic has a continuous use temperature of 800. Its coefficient of thermal expansion readily matches most metals and sealing glasses. It is nonwetting, exhibits zero porosity, and unlike ductile materials, won't deform. It is an excellent insulator at high voltages, various frequencies and high temperatures. And when properly baked out, it won't outgas in vacuum environments.

Machining

 MGC Machining tolerances are surprisingly tight, up to .0005". It can be machined to a surface finish of less than 20?in. and polished to a smoothness of 0.5μ. Configurations are limited only by available equipment and the experience of the machinist.

Sealing, Joining and Metalizing

 MGC can also be joined or sealed - both to itself and to other materials. - in a number of ways: metalized parts can be soldered together and brazing has proven an effective method of joining the material to various metals; epoxy produces a strong joint, and sealing glass creates a vacuum tight seal. Even a straightforward mechanical joint is possible. It can be thick film metalized using metal inks, or thin film metalized by sputtering.
