Product Description

Silicon nitride

Silicon nitride powder, Gray, An advanced inorganic non-metallic materials, It is widely used in the iron and steel smelting,
refractories, also it has a wide range of applicationsin high temperature sealing abrasive, such as wear rubber, plastics,
ceramics, etc. Main features: This product is a new material which generated in the specific atmosphere temperature,
it is divided into several grades: FD90、FD95、FD99、FD3N、FD4N.It has characteristics of high purity, high nitrogen content, and narrow particle size distribution,
high sintering activity.

Typical Performance Index:

Note: Our company provides different particle size and composition of silicon nitride powder as per users’ requirements,
including micron-scale silicon nitride powder.

Application:

FD99-α Silicon nitride and FD99-β Silicon nitride mainly used in coating and structural ceramics, etc

FD3N Silicon nitride mainly used in structural ceramics and others.
FD4N Silicon nitride mainly used in the photovoltaic industry.

As a new material in modern industry,FD90 Silicon nitride and FD95 Silicon nitride is widely applicable to
the industries of refractory,ferrous metallurgy,ferrous smelting, and horizontal continuous casting, for example:
stemming in refractory, iron hook material, three major items in horizontal continuous casting,
its products of crucible and protecting tube in ferrous smelting, as well as nitrogen alloy
reagent in metallurgy. Otherwise, 1,000-mesh silicon nitride also can be used as coating.
