Ceramics and Cermets Processing Exam
Questions and Answers 100% Solved
Ceramic metals divide into three categories: - ✔✔1. Traditional Ceramics:
particulate processing
2. New ceramics: particulate processing
3. Glasses: solidification processing
Particulate processes - ✔✔for traditional and new ceramics as well as
certain composite materials
Processing Overview for Traditional Ceramics - ✔✔Powders are mixed with
water to bind them together and achieve proper consistency for shaping
Condition of powders and part during 1. Preparation of raw materials 2.
shaping 3. drying and 4. firing
Traditional ceramic products: pottery, stoneware, dinner, bricks, tile
Raw materials consists primarily of silicate ceramics-clay
Preparation of Raw Materials in Traditional Ceramics Processing - ✔✔Most
shaping processes for traditional ceramics require the starting material to
be a plastic paste

, This paste is compromised of fine ceramic powders mixed with water
Its consistency determines the ease of forming the material and quality of
the final product
The starting raw ceramic material usually occurs in nature as rocky lumps.
Purpose of the preparation step is to reduce these rocky lumps to powder
Comminution - ✔✔Reducing particle size in ceramics by using mechanical
energy in various forms such as impact, compression, and attrition (size
reduction of ceramic powder)
Comminution techniques are most effective on brittle materials such as
cement and metallic ores
Two general types of commuinion operations: crushing and grinding
Crushing - ✔✔Reduction of large lumps from the mine or quarry to smaller
sizes for subsequent further reduction.
Several stages may be required Reduction ration in each stage is 3 to 6
times.
Crushing of minerals is accomplished by compression against rigid
surfaces or impact against surfaces.
Jaw Crusher - ✔✔Large jaw toggles back and fourth to crush lumps against
a hard, rigid surface
Roll Crusher - ✔✔Ceramic lumps are squeezed between rotating rolls
