Product Description

Home Electrical Microwave Magnetron Ceramic / Special Ceramic Parts

1. Description:

Alumina is the most well-known and most commonly used fine ceramic material. It has the same sintered crystal body as sapphire and ruby. It has been used for decades in electrical components for its high electrical insulation, and is widely used in mechanical parts for its high strength, and corrosion- and wear-resistance.It is the most well-known fine ceramic material for chemical and physical stability.Its producing process as below:

Powder Preparation Understanding how raw powder contributes to the final properties of fired ceramics is key to providing components that meet the challenges of your application.

Forming There are several basic forming methods such as Isostatic Pressing, Extrusion, Injection Molding, Mechanical Pressing.

Green Machining The machining of a ceramic in the unfired state is called green machining. Green machining of ceramics is done whenever possible since the machining of ceramics after firing is very costly.

Firing In order for ceramic to be hard and dense, they must be "sintered", or fired to high temperatures for prolonged periods of time in gas or electric kilns.

Coating / Glazing One of the reasons that parts are glazed is to make it easy to remove unwanted residue. For instance, spark plugs are glazed to reduce areas of potential arcing in high voltage environments.

Grinding & Cleaning Grinding and cleaning are part of the after firing operations, please find detailed descriptions for each process at the link above.

Metalizing & Plating We produce thick film metalization inks that utilize a Moly-Manganese (MoMn) refractory formulation designed for oxide ceramic bodies to provide one of the industry's strongest bond strengths.
