Diatomaceous earth were subjected to carbothermal reduction and nitridation in a flow of nitrogen containing various reducing agents; NH3, H2, CO, and CH4. It was found that a carbon plate or mathane are capable of reducing SiO2, but neither H2 nor CO. The effect of addition of powdered carbon to diatomaceous earth was also studied. Results were obtained in terms of the yields both outside and inside the whiskers.
