High-precision Silicon Carbide Ceramic Materials components for the 3C field.
3D glass is widely used in the 3C field. The molding process is an important part of the 3D glass. Under the temperature and pressure conditions of 800℃, stainless steel, graphite and tungsten carbide materials can’t reach the applicable standard. The latest developed silicon carbide material has high strength, good oxidation wears resistance and excellent heat conduction ability. It can solve the fatal defect of high-temperature oxidation deformation of stainless steel heating plate and graphite mold oxidation defect. At the same time, the low thermal conductivity and low expansion ceramic materials were developed to solve the difficulty of cooling deformation and reduce the energy consumption of the glass molding system.

High-precision Silicon Carbide Ceramic Materials components in photovoltaic and semiconductor fields

Silicon carbide ceramics with high-temperature resistance, high stiffness, low coefficient of thermal expansion and excellent chemical inertness, high temperature, high corrosion resistance, and high precision conditions in the photovoltaic and semiconductor industry are widely used. Silicon carbide etching disc has super-high thermal conductivity and ion corrosion resistance and improves the etching rate of the silicon wafer. Silicon carbide pipes with high temperature and wear resistance used in the transmission channel of production of high-temperature Silicon material, no pollution in the production process, ensure the quality of products.

The traditional silicon carbide kiln furniture is reactive sintering RBSiC and recrystallization sintered material RSiC. Because of the more than 10% free silicon, the use temperature of RBSiC material is not higher than 1350°C. and the RSiC material has 10% porosity and low strength, which cannot be used for high load. The pressureless sintered silicon carbide SSiC kiln furniture has high strength (high load resistance), high-temperature resistance (above I 5009C). high-temperature corrosion-resistant etc which make it widely used in high-temperature support and combustion components to roll bars, square beams, round pipes, square tubes, burning plates, fire nozzle, and other frame shuttle kilns and roller kiln. And it has an obvious energy-saving effect.
