Our Si3N4 plate and board can work in many kinds of difficult environment, such as strong acid and alkaline, high temperature,etc.
Si3N4 ceramic has very long lifespan, and because of it’s high wear resistance and low density, many plants use it instead of alloy steel, Zirconia, and aluminum ceramic.
Q: Is it possible to provide samples?
A: We can supply 1-2 samples, but we do not bear the shipping cost of the samples.
Q: How long is the delivery time usually?
A: Product delivery is subject to order quantity and processing requirements, and different product delivery times are inconsistent. Generally speaking, the delivery time of 1-2 common product samples is about 35 days.
