A method of producing an abrasive product consists of providing a mixture
of a mass of discrete carbide particles and a mass of cubic boron nitride
particles, the cubic boron nitride particles being present in the mixture
in an amount such that the cubic boron nitride content of the abrasive
product is 25% or less by weight, and subjecting the mixture to elevated
temperature and pressure conditions at which the cubic boron nitride is
crystallographically stable and at which substantially no hexagonal boron
nitride is formed, in the presence of a bonding metal or alloy capable of
bonding the mixture into a coherent, sintered product, to form the
abrasive product. The bonding metal or alloy comprises a combination of a
transition metal or a transition alloy and up to 40% by volume of the
bonding metal or alloy of a second metal which is a stronger nitride or
boride former than the transition metal or the transition metal alloy.
