Is silicon nitride Bioinert?

Silicon nitride (Si3N4) is a non-oxide ceramic used to make spinal implants. Ceramic materials are believed to be bioinert, (i.e., stable under hydrothermal conditions).

Is silicon nitride toxic?

Unusual Fire & Explosion Hazard: When heated to decomposition, silicon nitride may emit toxic fumes of ammonia and ozone. Contact with acids may generate flammable hydrogen gas.

What type of material is silicon nitride?

crystalline ceramic
Silicon nitride (Si3N4) is a covalently bonded crystalline ceramic.

What is the permittivity of silicon?

Is silicon nitride elastic?

Silicon nitride ceramics have a high Young׳s modulus [3]. Elastic constants of the silicon nitride ceramics depend on the porosity and, consequently, on the density. The elastic modulus data are given for silicon nitride ceramic with density 2.94 g/cm3.

How does silicon react with nitrogen?

At temperatures between about 1250 and 1400~ gaseous nitrogen reacts with solid silicon to form silicon nitride (Si3N4). At higher temperatures, nitro- gen encourages reaction with liquid silicon. Most of the research has been done using powder compacts of silicon as the starting solid.

Is silicon nitride ionic or covalent?

Silicon nitride (Si3N4) is a covalently bonded crystalline ceramic.

Is silicon nitride porous?

Besides dense silicon nitride-based ceramics also the porous form is intensively studied for bioapplications. Porous silicon nitride with a structure resembling that of cancellous bone is already commercially used as a spinal fusion implant with bone ingrowth rates similar to those reported for porous titanium.

Is silicon nitride a polymer?

Silicon nitride is an important structural ceramic due to its high-temperature proper- ties, its stability to oxidation, and its low thermal expansion coefficient [7]. Three general types of organosilicon polymers are used to generate silicon nitride, poly(sila- zanes), poly(carbosilanes), and poly(silanes).

What is the relative permittivity of silicon?

εis the permittivity of Si ε= 1.04×10-12 F/cm ε= K Sε 0, where ε 0 = 8.85×10-14 F/cm and K S = 11.8 is the relative permittivity of silicon

What is the permittivity of Si ε 0?

εis the permittivity of Si ε= 1.04×10-12F/cm ε= K Sε 0 , where ε 0 = 8.85×10-14F/cm and K
