    Abstract: Cellulosic materials such as wood chips, textile fibers and the like are treated to produce products such as particle board having enhanced fire and heat resistant properties. For example, wood chips are saturated with an eqimolar aqueous solution of monoammonium phosphate and diammonium phosphate. A metal hydroxide is added to the solution. The saturated wood chips are dried and mixed with a modified glue composition. The glue that which contains urea formaldehyde and/or phenolic resin is in powdered or brown marble form and dissolved in water. The treated wood chips and modified glue is then mixed, formed into a mat and placed under pressure at about 120° C. for 8 to 15 minutes. The pressure may range from about 300 to 400 psi.
