Product Description

High Purity 95% Alumina Metallised Ceramics for X-Ray Tube
 

Jinghui Ceramic is proficient in using the silver firing method to prepare metallised ceramic parts. The metallised ceramic products we produce have excellent air tightness. The high mechanical strength of the silver metallisation layer also extends the service life of the part.

Metallisation provides fabrication properties to ceramic parts that can then be easily brazed with common brazing alloys for a variety of applications. 




Comparison of ceramic metallisation Methods

You can see the common ceramic metallisation methods in the table below. Each method has its own advantages and disadvantages, and it needs to be considered comprehensively in practical applications to decide which method to use.
 

Common Metallisation Process	Process Description	Advantages	Disadvantages
Electroless Nickel Plating Method	Ceramic Body + Electroless Ni Plating	1. Uniform coating and small pinholes. 2. Low cost, suitable for mass production.	Low bonding strength
Silver Firing Method	Ceramic Body + Ag Coating	1. Silver has strong electrical conductivity and good oxidation resistance. 2. The fired silver layer is firmly bonded, and the thermal stability is good. 3. The process is simple and easy to implement.	1. Thin, discontinuous and uneven film layer. 2. Higher cost.
Mo-Mn Method	Ceramic Body + Mo-Mn Metallisation + Electroplating or electroless Ni plating	1. The most important one in the metal powder sintering methods. 2.  Mature and stable process, and high bonding strength. 3. To prevent oxidation and improve wettability, after the metallised Mo layer is sintered, a Ni layer can be plated on it.	The film layer is discontinuous, uneven, and rough.
W-Au Method	Ceramic Body + W Metallisation + Au Plating	1. Tungsten metallisation has the advantages of simple formula, and can meet some special requirements, such as alkali metal vapor resistance. 2. The gold layer is highly conductive and protects against oxidation and increased contact resistance.	The film density is not high.

About the silver firing method

The silver firing method is the earliest and most mature ceramic metallisation method. It is to apply a layer of Ag slurry (composed of Ag salt flux and adhesive) on the ceramic surface, and then sinter at high temperature to reduce Ag ions to monoplasmatic Ag, and infiltrate a layer of metallic silver on the ceramic surface. The following is the brief description diagram.
