Material Characteristics:
Silicon nitride ceramic is a structural ceramic produced from high-purity silicon nitride powder through gas pressure sintering. It features low density, high hardness, high strength, and outstanding thermal shock resistance, along with wear resistance, self-lubrication, corrosion resistance, high-temperature electrical insulation, and non-magnetic properties. It performs stably under harsh conditions such as rapid cooling and heating, high speeds, and strong corrosion, making it an ideal key ceramic material for extreme working environments.

Product Information:
Silicon nitride plates are homogeneous thin plates made from high-purity silicon nitride powder through tape casting, gas pressure sintering densification, and precision grinding. The plates fully leverage the combined advantages of silicon nitride material, including high strength, high hardness, thermal shock resistance, and corrosion resistance. They offer excellent flatness and dimensional accuracy, with no warping, cracking, or deformation under severe conditions such as high temperatures, heavy loads, and intense thermal cycling. They are an ideal material choice for high-temperature structural components and insulating parts.

Performance Parameters:
Bulk density ≥ 3.2 g/cm³, Vickers hardness ≥ 1500 HV, flexural strength at room temperature ≥ 700 MPa, fracture toughness ≥ 6 MPa·m¹/², thermal conductivity ≥ 80 W/m·K, dielectric strength ≥ 15 kV/mm, maximum operating temperature up to 1200 °C.

Product Dimensions:
Length and width can be precision-cut according to customer requirements. Products can undergo single/double-sided precision grinding, polishing, laser cutting, scribing, and other processes. Yuko Corporation can also customize non-standard thicknesses, plates with cavities, grooves, or hole structures based on drawings.

Product Applications:
Silicon nitride plates are widely used in high-temperature furnace linings, welding fixtures, wear-resistant liner plates, kiln insulation structural components, insulating parts for semiconductor equipment, hot-section components of aircraft engines, corrosion-resistant pumps and valves for the chemical industry, metallurgical continuous casting, and other applications involving high temperatures, strong corrosion, and heavy-load friction. They are an ideal high-performance structural ceramic plate for harsh industrial environments.
