Boron nitride ceramics have advantages of high-temperature resistance, use temperature of 2000 degrees and alumina does not exceed 1700 degrees. The heat shock resistance is very good, and the boron nitride ceramics will not crack, 1000 degrees of furnace heat out for 20 minutes to blow the air and cold repeatedly hundreds of times will not crack. Aluminum oxide ceramics are urgently cold and hot is easy to crack. Corrosion resistance, acid-alkali resistance, electric insulation strength is 3-4 times that of alumina ceramics. Boron nitride ceramic-metal materials do not react nonbonding such as black ferrous, iron, copper, stainless steel, bismuth, germanium, aluminum, antimony, tin, cadmium, lead, nickel, zinc, brass, indium, magnesium; glass melt, sodium glass, ice crystal, etc. Silicon molten salt: slag fluoride does not react and does not bond, can be used as its high-temperature sintering melting holding container, the crucible, sintering plate, etc. Boron nitride is prone to moisture absorption and should not be placed in wet areas when the crucible is unused. Sealed, can not be washed, dirty, and wiped directly with sandpaper. All sizes can be processed according to the customer's requirements.

Boron Nitride Crucible Applications

Boron nitride crucible from Heeger Materials can endure high temperatures in the high vacuum environment, plus it has excellent corrosion resistance and electrical resistance. Therefore, boron nitride ceramic product is an ideal choice in a wide range of industries, such as:

-Electric insulators in vacuum system
-Insulators for high-temperature furnace
-Spacers for glass melting
-Boron Nitride parts for ion injection equipment

Tips When Using Experimental Boron Nitride Crucible

 1 The use temperature in the air can not exceed 1000 degrees, more than 1000 degrees of boron nitride and oxygen contact surface will oxidize and peel off.

2. Boron nitride is easy to absorb moisture, the crucible cannot be stored in a wet area, not washed, it can be directly wiped with sandpaper or scrub with alcohol.
