Non-metallic ceramic materials and composites whose softening points are above 1,500 ° C are defined as refractory material.
Refractory materials, which are separated into shaped (e.g. stones, blocks, slabs) and unshaped (e.g. cement, mortar, concrete) materials, are mainly used in high temperature industrial processes.
To determine the requested strength Toni Technik provides intelligent test solutions:

The plasticity tester is designed for the determination of the workability of ceramic materials. The plasticity value according to Pfefferkorn is determined by measuring the plasticity of a specimen between a fixed lower bearing plate and a free falling upper brass plate. Advantages ✓ Reliable evaluation of characteristic values ✓ Simple operation
-
Operating Principle
The viscosity tester type Lehmann is designed to determine the viscosity of glazing and clay slips. The time is measured that a defined amount of test material needs to run through a nozzle with a specific cross section into a volumetric flask. Subsequently the viscosity value can be determined comparing the time with such a slip of known consistency needs.
Advantages
✓ High repeatability ✓ High accuracy ✓ Simple technique and handling ✓ Simple and quick measuring procedure (advantageous for test series and quality control)
