Refractory Insulating Locating Zirconia Ceramic Stopper Blocks Through Threaded Hole
Alumina Ceramic or Zirconia Ceramic, for Alumina, the purity would be 95% or 97% or 99.99%,
For Zirconia, the purity usually be 95% , the balance 5% sould be additive material.
We also can provide electronic ceramics, the material is Aluminium nitride , it is a very special ceramic material, there are both excellent Electrical insulation and Thermal conductivity. This Aluminium nitride ceramics widely be taken in electronic application.

MingRui Ceramic can make all the size as bellow:
shape in cylinder, diameter 0.3-100 mm, length up to 300 mm;
shape in plate, length and width up to 100 mm, thickness0.2-50 mm;
shape in through hole, Diameter 0.10-100 mm;
shape in blind hole, diameter 0.45-100 mm;
shape in Groove or slot, depth up to 50 mm, width 0.1 mm at least.
Typical for the applications of technical ceramic materials is a frequent requirement for other non-electrical properties such as:
- Mechanical strength
- Thermal resistance
- Thermal shock resistance
- Thermal conductivity
- Corrosion resistance
- Production of ultrahigh-vacuum-capable joints with metals
A key strength of this class of materials is the demand-driven combinations of the above-mentioned properties. In addition comes the possibility to optimize properties for a specific application by means of appropriate doping and therefore to tailor materials to requirements.
For instance, the zirconia ceramics used for λ sensors can be optimized to maximize their strength without compromising their suitability for use as oxygen sensors as only one electrical signal must be recorded, which can be evaluated on the basis of appropriate calibration. With the selective modification of the chemical composition of this material, maximized electrical conductivity can be obtained along with an acceptable level of strength. As a result, this anionic conductor can be efficiently used as electrolyte for SOFCs (high-temperature fuel cells).
