Ceramics
Thermal Properties
Thermal Expansion (Linear Expansion Coefficient)
Used to evaluate the degree of fine ceramics' expansion by heat, the higher the value, the more it will expand or shrink due to temperature differences.
Thermal Conductivity
Used to evaluate the fine ceramics' ability to transfer heat, the higher the number, the more heat is transferred.

Porous Ceramics
Mechanical Properties
Bending Strength
Used to evaluate fine ceramics' resistance to bending stress, the higher the value, the harder it is to bend.
Thermal Properties
Thermal Expansion (Linear Expansion Coefficient)
Used to evaluate the degree of fine ceramics' expansion by heat, the higher the value, the more it will expand or shrink due to temperature differences.
ASUZAC conducted an acid corrosion resistance test for the following ceramics: Alumina (AR), Silicon Carbide (ASiC), Corseed (ACTR), Alsima L (ARSM-L) and Porous Alumina (AZP-50).
A piece of these ceramics was immersed into sulfuric acid, nitric acid, hydrochloric acid, phosphoric acid, hydrofluoric acid, and sodium hydroxide.
Experimental conditions:
Melting temperature 100℃
Immersion time 24 hours
Specimen size 3 × 4 × 39mm
Solution concentration: 3 mol / l , sulfuric acid 3 mol / l , nitric acid 3 mol / l, hydrochloric acid 3 mol / l , phosphoric acid 3 mol / l , hydrofluoric acid 6 mol / l
