Our Silicon Nitride powder, gray,
is new material which produces under the specific high temperature and high
pressure, the main component of it is Silicon Nitride. It occupies 80% --97.5%
of the total Ingredient, The products of different purity and composition can be
produced to satisfy user's need.
1. Principal Characters
(1)
Fine corrosion and erosion-resistance, thermal shock resistance,
wear-resistance; It can be employed under the temperature of 1900 Celsius
degrees.
(2) Fine disintegration resistance, rather stable chemical
ingredient and thermal conductivity.
(3) For containing nitride, this
product possesses the properties of little expansion ratio, high thermal
conductivity, high degree of firmness, non-contractive when heating up.
(4)
High intensity and durable.
(5) Under high temperature, an oxide film will
develop on the surface, so as to protect inner material from being affected by
chemical reactions.
2. Key Properties
