Audited Supplier Product Description
Anhui Yuanchen Nano Silicon Nitride Ceramic Powder Si3N4 Manufacturer
Feature
1.High purity, small particle size distribution, high specific surface area
2.Insoluble in water,but Soluble in hydrofluoric acid
3.A very important structural ceramic material and superhard material
4.Have features of lubricity,abrasion resistance,strong corrosion resistance and high temperature oxidation resistance.
5.Can resist thermal shock.When heated in the air to more than 1000ºC,it will never rupture with cold snap and severely heating.
6.Silicon nitride ceramic devices have low ceramic temperatures,with good dimensional stability and high mechanical strength.
Precautions
This product should be stored in a cool, dry room to avoid heavy pressure.Powders that have not been surface treated should not be exposed to air to avoid moisture absorption and agglomeration, which may affect dispersion and use.

Anhui Yuchen Environmental Production Science&Technology Co,Ltd,which was established in 1997 ,is a national high-tech enterprise with ISO9001:2008,ISO14001:2004,Hazardous Waste Management License, specializing in dust filter bag,filter fabric,filter cage,honeycomb catalyst and other spare parts used for the dust collectors.More than 200 skillful workers,German production technology,strict material selection,modern production equipment and managements enable us the ability to produce 10000 square meters filter cloth,3000 filter bags and 1000 filter cages per day.Exported to Japan, Korea,Brazil,Pakistan,Chile,Columbia,Turkey,South Africa,Malaysia,India,Philippines and many other countries and regions.We are not only the supplier for filter bags,we are also the solution supplier for your removal projects,besause we have 7 Senior Engineers designing to meet the requirements of your industry environment
With more than 20 years experience and specialized in filter fabrics and filterbags ,Anhui Yuan Chen filteris developing air filtration with professional teams.Now, Yuan Chen has output of near US$40 million annually, prepared for the listing of stock market. We specialize inlow and high temperature dust filter fabrics like PPS, composition of PPS and PTFE, NOMEX,Fiberglass, PET, Acrylic etc. Our filter fabric can guarantee the ultra clean,emission( under 10mg).We also have our own laboritory-CNAS,all products will be tested before delivey.
Packing detail
nano silicon nitride powder is available of 100g/bag, 500g/bag, 1kg/bag, according to customer's requirements.
1.Manufacturing precision structural ceramic devices:widely used in area of Metallurgy, chemical, machinery, aviation, and energy industries etc,balls and rollers using rolling bearings,Sliding bearing sleeve valve as well as the structural components required for wear resistance, high temperature resistance and corrosion resistance
2.Surface treatment of metals and other materials:Such as molds, cutting tools, turbine blade turbine rotors and cylinder inner wall coatings.
3.Preparation of high performance composites:Such as metal, ceramic and graphite-based composites,Rubber, plastics, coatings, adhesives and other polymer matrix composites.
4.Application in high abrasion Resistance rubber;Add 1-3 parts of Si3N4 powder to the bellows pipe whose main adhesive material is EPDM.The durability test of the product can be improved to from 200,000 time to more than 1 million times,and the performance is improved by 5 times.
5.Application of wear-resistant composite plating on metal surface:Silicon nitride has high hardness and low sliding friction coefficient.Its mechanical properties are higher than other ceramic materials.Compared with metal materials, the room temperature strength of silicon nitride can be maintained above 800 °C.Even between 1200 and 1400, it will remain considerable strength. If used in harsh conditions, it is advisable to coat the surface with Si3N4 metal composite
6.Application of absorbing infrared textiles:Silicon-based nano powder is nylon, polyester enhance electrical conductivity.Nano-silicon nitride has the absorption rate of the infrared absorption band of the human body above 97%, which is the best absorption infrared ultra-fine textile additive..
7.Application of polysilicon and single crystal demoulding agent:When polycrystalline silicon and monocrystalline silicon are smelted to cast ingots, the ceramic powder is used for demoulding between silicon melt and quartz crucible
8.Application in LED luminescent material:Nanometer Si3N4 phosphors belong to luminescent materials with individual luminescence centers (cerium Ce3 europium Eu2). The energy transition process belongs to f-d transition
9.Application of nano silicon nitride in other industrial fields:High performance wear resistant, high temperature resistant rubber seals and tires,in anti-corrosion refractory coatings, high temperature insulating electronic materials and inorganic ceramic lubricating oils.It can also be applied to structural ceramics and inorganic composite materials.
