Tabular Corundum 0-0.2mm For Filling Ceramic Resistors Component

Tabular Alumina For Filling Ceramic Resistors Component

What effect add tabular corundum in ceramic resistors?

The main functions include improving high temperature stability, enhancing mechanical strength, improving insulation performance and extending service life.

Improved High-Temperature Stability

Tabular alumina has a high melting point (typically ≥1800°C), maintaining material stability in high-temperature environments and preventing structural changes caused by thermal expansion or contraction.

Enhanced Mechanical Strength

Its dense crystal structure and high hardness (Mohs hardness 9) significantly enhance the compressive and flexural strength of resistor components, extending their service life.

Improved Insulation Performance

Tabular alumina has a low dielectric constant (approximately 8-10) and high resistivity (10⁰-10⁰Ω·m), effectively reducing electromagnetic interference and improving the insulation performance of resistor components.

Extended Service Life

Its strong corrosion resistance protects against acid and alkali attack, reducing material degradation caused by environmental factors.

Description:

White tabular corundum has good heat resistance and good volumetric temperature shock ability. Crystal tabular corundum powderhape plate to increase the mechanical strength of the particles; internal structure full of closed pores, high bulk density, low apparent porosity and water absorption to reduce the amount of reused fluids; With good physical properties such as: high refractory, excellent thermal shock resistance, low shrinkage and good strength under thermal load, etc. Meanwhile, high cleanliness preventing damage to machines. Haixu abrasives is your best choice as refractory material/ceramic material and insulation materials.
