Q: What is your minimum order quantity (MOQ)?
A: Our minimum order quantity (MOQ) depends on many factors such as product, material, dimensions, etc.

Q: Do you provide free samples?
A: Yes, we are pleased to provide a free sample for your initial evaluation of our materials if we have the sample in stock and if its cost is bearable to us.

Q: Do you accept a trial order before a bulk purchase?
A: Yes, we welcome your trial order to verify our quality before your bulk purchase.

Q: What is your production time?
A: Our production time depends on materials, production methods, tolerances, quantity, etc. Normally, it takes 15-20 days if we have stock material, and it takes 30-40 days if we don't. Please share your specific requirements with us, and we will quote the fastest production time.

Q: What are your payment terms?
A: Our payment terms are T/T, L/C, and PayPal.

A: We pack the ceramic products tidily with foam protection inside the carton, plastic box, and wooden box.

Q: Do you accept custom orders?
A: Of course, most of our orders are custom products.

Q: Would you provide an inspection report and material test certificate for our order?
A: Yes, we can provide these documents upon request.

Silicon Nitride (Si3N4) is the most adaptable technical ceramic material in terms of mechanical, thermal, and electrical properties. It is a high-performance technical ceramic that is exceptionally strong and resistant to thermal shock and impact. It outperforms most metals at high temperatures and has an excellent mix of creep and oxidation resistance. Furthermore, due to its low thermal conductivity and great wear resistance, it is an outstanding material capable of withstanding the harshest circumstances in the most demanding industrial applications. When high-temperature and high-load capabilities are required, Silicon Nitride is a suitable alternative.
