Silicon nitride powder has many uses. As a new material in modern industry, silicon nitride powder is widely used in ceramics, refractory, steel metallurgy, non-ferrous smelting, rubber and other industries.
In the non-ferrous industry, it has excellent corrosion resistance and wettability properties and is widely used. 2) In the steel industry,
A. Silicon nitride coating can effectively solve the problem of oxidation and burning loss during the heat treatment of steel billets. Experimental results show that nano-silicate antioxidant coating can prevent oxidation from 3%-5% of oxide scale produced by ordinary hot-rolled plates to 0.1%-0.8%, and reduce 1% of oxide scale produced by stainless steel hot-rolled plates. -3% oxide scale dropped to below 0.2%.
B. Silicon nitride gun mud. The gun clay containing silicon nitride will play an effective role in sintering activation, corrosion resistance and anti-splitting. When used in the furnace body or electric furnace, it can seal the blast furnace mouth more stably and is very Easy to cut.
C. Silicon nitride has good applications in HRB400 high-strength hot-rolled steel bars. Si3N4 is used as a nitrogen-increasing agent, combined with FeV, to produce V microalloyed Grade III steel bars. The steel bars have excellent and stable properties. It is a new alloying process for producing HRB400 Grade III steel bars.
D. Silicon nitride is second only to boron nitride in terms of nitrogen content per unit mass, and its price is low, making it very cost-effective in adding nitrogen.
3) Because this product has good applications in new ceramics and composite materials, it can improve its corrosion resistance, thermal conductivity, thermal shock resistance, wear resistance, high strength and other properties.
