Product Description Product DescriptionCeramic dosing pumps are specially developed for the dosing of highly abrasive materials. These pumps are a precision pair consisting of a solid ceramic body and a piston. The high hardness of the ceramic and the absence of elastomer or liquid seals enable ceramic dosing pumps to operate for many years without leakage or pressure loss due to material leakage from the gaps between the piston and the cylinder. The pump can be manufactured from silicon matrix silicon carbide material according to the drawings. FeaturersPressureless sintered silicon carbide is a type of silicon carbide ceramic material prepared by the pressureless sintering process, with the following significant advantages: - Excellent mechanical properties: It has high hardness and strength, good flexural strength and fracture toughness, can withstand large mechanical stress, and is suitable for scenarios requiring wear resistance and high strength.- Good high-temperature resistance: It can maintain stable performance in high-temperature environments, has strong oxidation resistance, can work for a long time at temperatures above 1600°C, and is suitable for high-temperature structural components.- Outstanding corrosion resistance: It has strong resistance to corrosive media such as acids and alkalis, and performs stably in corrosive environments such as chemical industry and metallurgy.- Lower cost: Compared with processes such as reaction sintering and hot-press sintering, pressureless sintering does not require complex pressure equipment, has higher production efficiency, and helps reduce the manufacturing cost of materials.- Good dimensional accuracy and shape flexibility: It is easy to prepare components with complex shapes and precise dimensions, and can meet the diverse needs for component shapes in different scenarios.Detailed PhotosProduct ParametersDifferent SiC products Parameter Comparison UnitDataRBSiC (SiSiC)NBSiCSSiCRSiCSiC content%85809998.5Free Silicon content%15000Max TemperatureoC1380155016001650Densityg/cm33.022.723.12.60-2.74Porosity%012015Bending strength 20oCMpa250160380100Bending strength 1200oCMpa280180400120Modulus of elasticity 20oCGpa330220420240Modulus of elasticity 1200oCGpa300//200Thermal conductivity at 1200oCW/m.k45157410Coefficient of thermal expansionK-1x10-64.554.14.8HVkg/mm2250025002800/ Corrosion test data for liquids of different materialsTest environmentCorrosive weight loss (mg/cm2yr )conc.ReagentTemperatureSSiCRBSiC (SiSiC)Tungsten carbide wt%°CNo Free SiSiC (12% Si)6% CoAluminum Oxide 99%98% H2SO41001.855>10006550% NaOH1002.5>100057553% HF25<0.27.982085% H3PO4100<0.28.855>100070% HNO3100<0.20.5>1000745% KOH100<0.2>100032.7225% HCl70<0.20.98501610% HF & HNO325<0.2>1000>1000 ExplainTest Time:125 to 300 hours of submersive testing, continuously stirred.Corrosion Weight Loss Guide:>1000 mg/cm2 yr Completely destroyed within days.100 to 999 mg/cm2 yrNot recommended for service greater than a month50 to 100 mg/cm2 yrNot recommended for service greater than one year10 to 49 mg/cm2 yrCaution recommended, based on the specific application.03 to 9.9 mg/cm2 yrRecommended for long term service<2 mg/cm2 yr Recommended for long term service, no corrosion, other than as a result of surface cleaning, was evidenced.ApplicationDue to its excellent mechanical properties, high-temperature resistance, corrosion resistance and other characteristics, pressureless sintered silicon carbide has a wide range of applications, mainly including the following categories: - High-temperature industrial field: It can be used to manufacture high-temperature furnace tubes, thermocouple protection sleeves, high-temperature structural parts, etc. It can work stably in high-temperature environments and meet the high-temperature process requirements of metallurgy, ceramics and other industries.- Mechanical wear-resistant field: It is suitable for making wear-resistant pipes, valves, bearings, seals, etc. In material transportation and wear equipment in mining, electric power, chemical industry and other industries, it can effectively improve the service life of components.- Chemical anti-corrosion field: Due to its strong corrosion resistance, it can be used for linings of chemical reaction kettles, corrosion-resistant pump bodies, pipes, etc., to resist the erosion of corrosive media such as acids and alkalis.- Energy field: It can be used as heat absorber components in solar thermal power generation, as certain high-temperature resistant and radiation-resistant structural parts in the nuclear energy field, and also for preparing key components of fuel cells.- Semiconductor field: It can be used as high-temperature carriers, wafer trays, etc. in the semiconductor manufacturing process to meet the requirements of high-temperature processes and clean environments.How to orderOther Related Products
