Production Process

How Our Ceramic Parts are Produced?

Metallized ceramic structural parts are widely used in the fields of new energy vehicles, electronics, semiconductor packaging and IGBT modules.

Our product production is mainly divided into 3 steps, forming - finishing - metallization. The production flow chart is shown below.

What are the Methods of Metallization of Ceramic Structural Parts?

The metallization method of ceramic structural parts is mainly to sinter a layer of metal film on the ceramic surface to achieve the purpose of ceramic metallization.

Common metallization methods are shown 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 Metallization 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 Metallization + 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 metallized 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 Metallization + Au Plating	1. Tungsten metallization 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.

Introduction to Mo-Mn Method

The Mo-Mn method is to coat metal powders such as Mo powder and Mn powder on the ceramic surface, and then sinter at high temperature in a reducing atmosphere (hydrogen gas), thereby forming a metal layer on the ceramic surface. Because Mo and ceramics have similar thermal expansion coefficients, the thermal stress after bonding is small, so the bonding strength between the metal film and ceramics is high.

The following is the general process of the Mo-Mn method applied to the surface of the ceramic structural parts.
