Silicon Nitride (Si3N4) is a relatively costly, high-temperature, structural ceramic

used where heat resistance, hardness, and strength are a premium.
 It is very hard, and therefore can be used in high wear applications or applications requiring a fine surface polish.
Silicon Nitride is fabricated using either sintering, reaction bonding, hot pressing, or hot isostatic pressing.
The material properties resulting from these processes vary considerably.

As critical part in rod pump, silicon nitride ceramic rod is widely used in electrical industry, ceramic industry, oil industry, food industry, medical industry, chemical industry etc. to replace metal rod.

it is one kind of technical ceramic materials which has very good performance in high temperatrue.

Its mechanical strength can be kept up to 1200ºC. Its hardness and wear resistance performance ranks high
among all technical ceramic materials.

It has high electrical resistivity, high dielectric constant and low dielectric loss, is a choice for electrical insulation.

Furthermore, it has good chemical stability and resistance to oxidation.

As a result, silicon nitride ceramic has the best comprehensive performance and most wide application in high
temperature field.

FAQ

1:What products and service can you offer us?

Answer: With the development more than 20 years, now we have 6 business division and we
are supplying Quartz Glass (Tube, Rod, Plate and customized parts), optical glass and cuvette, and also various precise ceramics,porous ceramics and refractory ceramics. We have the full processing line for ceramic thick film resistors, far infrared ceramic glass heating panel, quartz tube/ceramic plate ozone generator,porous metal fiber felt and polyester fiber cotton products. For all the products, we can design and customize according to the clients' demand.

2: Before mass order, can you offer samples? How will you charge for them?

Answer: We are willing to offer samples to lower your purchasing risk. Generally, if from inventory, we can deliver out within 3days, however if need processing, we can deliver out within 15days. For some difficult items, the delivery time will be decided by its grade of difficulty. For some low value items, we can offer free sample, however we would like you
to afford the freight cost. For customized products, we need to charge the developing cost.

3: What test report or certificate can you offer? What achievements have you made in research and development?

Answer: Till the end of 2021, we have passed many ROHS, CE, MSDS tests and also the ISO9001 authentication. We have 8 registered trademark and 25 patents. Also we won the title of China High-tech Enterprise and Jiangsu Private Science and Technology Enterprises.

4: Do you have any agent in our area? Can you export your products directly?

Answer: Till the end of 2021, we haven't authorized any company or person as our regional agent. From 2008, we have the export qualification and professional export team, and till the end of 2021, we have exporting our products to more than 108 countries and regions, and our clients can contact us and purchase our products or service directly.
